Does RemoteZilla work with Microsoft Windows 7 and Vista?

Windows 7 Remote Support SoftwareYes! It is fully Windows 7 and Vista compatible and runs as an application or as a service allowing you to log the user off/on or boot to safe mode.



Why do I need remote support?

Mobile working ToolkitDeb Shinder of ZDnet wrote a great article
"Facing the challenge of an expanding remote user base"
that best explains why you need remote support.



What if I need to change my IP address or port number?

If you need to change your IP address, DNS, DDNS simply rebuild your customer module with the new address and port number.

If you use web based configuration files, you can update them with your current IP address and port anytime you wish or if you use a DDSN service such as or, you simply update the address at their website.



What if I want to change may password or other options?

If you want to change your password or wish to add or remove any other feature simply rebuild your customer module with the new password or options supported by your package. Note: If you change your encryption you will need to ensure none of your customers try to connect with the old customer module.



Can all of my technicians use the same public address and port?

Yes! The RemoteZilla reverse proxy software supports Relay and Redirect Mode which lets all of your technicians and instructors customer modules use the same public IP/DNS/DDNS address and the same public port even if they are at different locations and on different networks around the world. This is important to allow all of your technicians to use port 443 or port 80 for better customer firewall penetration.  It's also useful if you have a limited number of ports you can forward in your NAT router or firewall and provides less risk to your network by reducing the number of ports left open.
All technician stations can use the same public address and port simultaneously!



What if I need to add additional technicians?

When you add additional seats, you only pay the listed additional technician price. There is no time limit for the purchase of additional technician seats.



What is Forced Reboot / Emergency Reboot?

Forced Reboot aka Emergency Reboot allows you to force a remote system to reboot if it is not responding to mouse or keyboard inputs or if the remote desktop has crashed. After the system reboots, it will automatically reconnect back to your technician before the logon prompt if running with administrative rights
Caution: This will force applications to close or terminate them which may result in loss of application data so only use this in an emergency.



Does RemoteZilla work with terminal services or remote desktop?

Yes! The RemoteZilla viewer and RemoteZilla reverse proxy software will work in a Terminal Services / Remote Desktop connection session without sacrificing any functionality or features.



Does RemoteZilla work with Microsoft Small Business Server (SBS)?

Yes! RemoteZilla will allow you to support customers that are behind a Microsoft Small Business Server (SBS) or Microsoft Internet Security and Acceleration Server (ISA) as long as you use port 443, port 80 or another port that is not blocked to outbound connections.



Does RemoteZilla work with the Windows XP Personal Firewall?

Yes! The RemoteZilla customer module (server) automatically configures the Windows XP Internet Connection Firewall (ICF) to allow the server to connect to the remote technician without disabling it's firewall protection with no prompts or input required by the technician or the customer. This is important since the built-in firewall component of Windows XP is turned on by default by the Windows XP Service Pack 2 (SP2). The original firewall configuration is automatically restored with no input required by the technician or the customer when the session is ended and the customer's system is never exposed to the internet without firewall protection. This is just one of the many industry firsts RemoteZilla offers.



Does RemoteZilla work in Safe Mode?

Yes! It works in safe mode and you can even re-boot the remote system into safe mode and it automatically re-connects back to your workstation before the logon prompt allowing you to remove spyware, viruses and troubleshoot Windows hardware drivers even if the customer is away from their computer.  This is just one of the many industry firsts RemoteZilla offers.

RemoteZilla works with Windows running in Safe Mode



Is Windows Administrator rights required to run RemoteZilla?

No! Windows administrator rights are NOT required. It works even if the remote user is logged on to Windows with a "Guest" account with no privileges to create folders or write to the registry. However, when running in such a restrictive environment, RemoteZilla will not be able to auto-connect on reboot and logging off the user will terminate the service.



Can I have multiple technician stations in a single support file?

Yes!  You have several Multi-Technician modes allowing you to place a single link on your website for any customer to connect to any support person. The customer downloads a single support file for unlimited technician stations, The technician number is selected by the customer via a dialog box or web based configuration or the parameter can be passed on the command line for use in scripts or other programs. To avoid scrolling through long lists of names, it simply asks the remote customer for the technician number or name of the technician to connect to. This allows you to have hundreds or thousands of technician stations in a single customer module. If you pass the technician parameter on the command line, it will not prompt the customer. This does not present a prompt after installation, re-boot or logoff/logon..



Can I use RemoteZilla if I don't have a static IP address?

Yes! Dynamic DNS Providers - You can use a dynamic DNS provider such as the free, No-IP.COM or that are supported by most new broadband routers to allow your customers to connect to your dynamic IP address using a static DDNS name or forward it to a temporary location no mater where you are. You simply update the IP address of your or DynDNS URL by clicking a link on the or website or you can keep it updated automatically by running the no-ip DUC program or using the DDNS update function built-in to many broadband routers.
You can also use web based configuration files and auto-update them with your current IP address.



Do you sell a Remote start program for RemoteZilla?

No, we don't sell one, it is built-into the software

RemoteZilla also has a built-in Delayed Connect feature which is less flexible but more secure,  and preferred by most remote customers. It requires the remote customer to initiate each session first, then you dynamically signal it to connect at a later date or time when you are ready to begin.  You can reboot the remote computer, log off/on switch between safe-mode and normal boot but once you have ended the session and uninstalled the software, it's over, you cannot start it un-invited.  This is not the same as Remote Starting which can be initiated at anytime without the customer's knowledge.



Does RemoteZilla trigger XP Data Execution Prevention (DEP)?

No! RemoteZilla does not trigger DEP.
We recommend running DEP at it's highest setting (see note below) to help prevent damage from malicious programs.

Understanding Data Execution Prevention

Data Execution Prevention (DEP) helps prevent damage from viruses and other security threats that attack by running (executing) malicious code from memory locations that only Windows and other programs should use. This type of threat causes damage by taking over one or more memory locations in use by a program. Then it spreads and harms other programs, files, and even your e-mail contacts.

Unlike a firewall or antivirus program, DEP does not help prevent harmful programs from being installed on your computer. Instead, it monitors your programs to determine if they use system memory safely. To do this, DEP software works alone or with compatible microprocessors to mark some memory locations as "non-executable". If a program tries to run code—malicious or not—from a protected location, DEP closes the program and notifies you.

Is it safe to run a program again if DEP has closed it?

Yes, but only if you leave DEP turned on for that program. Windows can continue to detect attempts to execute code from protected memory locations and help prevent attacks. In cases where a program does not run correctly with DEP turned on, you can reduce security risks by getting a DEP-compatible version of the program from the software publisher. For more information about what to do after DEP closes a program, go to 

By default, DEP is only turned on for essential Windows operating system programs and services. To help protect more programs with DEP, select Turn on DEP for all programs and services except those I select.



Can I use RemoteZilla from alternate locations such as hotels?

Yes! Here are several methods you can use.
  • The easiest way is to use the RemoteZilla Repeater (included) which will let you and your customers connect outbound from your location so neither of you do not have to deal with opening firewall ports.
    RemoteZilla Reverse Proxy - This simple to use Windows 95/98/NT/2000/XP/2002 based software solution is included in RemoteZilla for free. It acts as a connection repeater, redirector, proxy or gateway. You only need to forward 2 ports through your company or residential firewall/gateway/proxy to one machine, one for inbound RemoteZilla Viewer connections and one for inbound RemoteZilla Server connections. This will allow you to connect to up to 20 customers simultaneously with RemoteZilla from outside or inside your network or from an off-site location. You can have more than one instance of the repeater running if you need to allow more than 20 multiple connections simultaneously. If installed outside your company firewall or port forwarded to, it will allow you to connect to RemoteZilla from behind host firewalls that you do not have administration privileges to, such as those in hotels, convention centers and satellite networks. This is a good short-term solution for technicians that primarily provide support from inside the company network and do not want the expense or security risks of setting up a dedicated hardware VPN gateway that gives full access to your internal network. Since both the RemoteZilla Server and RemoteZilla Viewer only allow outbound connections, your network security is maintained.
    You can setup the repeater at your home or office and open ports to the repeater as you would normally do with the viewer. You connect out to the repeater using your RemoteZilla viewer from a hotel or company firewall where you don't have access rights to configure the firewall. If you are using a dynamic DNS provider (DDNS) in this situation, you would leave the dynamic DNS (,, etc.) address pointing to your repeater address back at your home or office. The customer module and your viewer both connect outbound to the repeater, so there is no need to open ports on either end.
    When you are back at the location where the repeater is and want to connect directly and not use the repeater, you simply close the repeater and run the viewer in listen mode as normal, the customer simply presses the "skip" button at the (optional) ID code prompt when they run the customer module and it connects outbound directly to the technician's listening viewer. This makes things much simpler since the same customer module is dual-compatible with both viewer mode and repeater modes without running separate customer modules.
  • Hardware VPN Appliance / Router / Gateway - If you're going to be providing support primarily from alternate locations, the best long-term solution is to install a dedicated VPN gateway device such as those from Netscreen, Cisco, SonicWALL and Avaya. Prices range from about $50 to $4500 or more depending on brand and sophistication of the device. If you only need a few concurrent VPN connections, you may already have a firewall or router with VPN capabilities, such as the Linksys, SMC Barricade, D-Link, NetGear or Netopia broadband routers that might satisfy your needs. A good VPN server is all you need to connect to and receive any RemoteZilla connection from/to any other RemoteZilla almost anywhere in the world. Simply setup the VPN capable router or firewall to forward port traffic to the VPN connection the same way you would forward a port to any other computer on your network, then establish a VPN connection to the device from the Windows machine you are providing support from and you're done.
  • Software based VPN using the Built-in Windows 2000 / XP VPN Server, OpenVPN and/or SSH or Putty - If you really want or need to use VPN and don't want to buy a hardware VPN appliance or router, both Windows 2000, Windows XP and Windows 2003 have the built-in capability to act as VPN server or VPN client and the free OpenVPN, SSH and SCP and Putty for Windows 9x, NT, ME, 2000 and XP allows you to port forward secure sessions Below are links to some excellent step-by-step instructions and documentation on setting up the services.

Is RemoteZilla Secure?

Yes! The RemoteZilla session must be initiated by the customer unless you pre-install the RemoteZilla RemoteStart utility. RemoteZilla does not accept inbound connections so no one can can access or initiate access to the customer's computer remotely. RemoteZilla uses industry standard end-to-end RC4 encryption to ensure data security, plus the data stream of RemoteZilla is compressed. To decode the data, a hacker would need to obtain the encryption key, have knowledge of when the session was happening, have access to the stream of data and then know how to decode the compressed stream before they would finally be able to see the session. This would be very difficult.

The RemoteZilla Server and RemoteZilla viewer uses optional end-to-end MS RC4 Stream Encryption. You have the option of using 40 bit, 56 bit or 128 bit key encryption so your sessions are secure. Unlike similar software, RemoteZilla does not allow inbound connections that hackers can exploit. The RemoteZilla Server is not capable of allowing inbound connections and the RemoteZilla Viewer does not provide server privileges to the technicians machines, even with the RemoteZilla Viewer in listen mode, permission from the technician (physically clicking the the accept incoming session button) is required before any connection is established. This helps maintain internal security on both ends, your network security is maintained.



Can the RemoteZilla Proxy relay connections into my network?

Yes but only if you enable it. For security we recommend using the default option of OFF unless you specify the internal workstations to allow. If you specify a list of acceptable relay destinations it will not allow connections to be relayed to any other internal address. For security, it only allows connections between the RemoteZilla viewer and RemoteZilla customer (server) modules any other connection methods are rejected.



Do we need a separate license for each customer that we support?

NO! RemoteZilla pricing is based on the number of computers you wish to provide support from, not the number of customers you will be providing support to, so you only need one RemoteZilla package to support an unlimited number of remote computers from one technician station..



Do I need a website to use RemoteZilla for customer support?

NO!  You can email the customer support module to your customer or send it to them on CD, floppy disk or other removable media. The only requirement is you and your customer must have internet access to establish a connection.
However, if you use web based configuration files or the delayed start option, you will need a website since these features were designed to be used primarily by PHP/ASP/Perl/Java/CGI powered web pages but the files can also be uploaded via FTP.



Does RemoteZilla need 3rd party services to establish a connection?

NO!  RemoteZilla uses direct point-to-point communications initiated by the remote computer to connect directly to your support technician's computer.  It runs entirely on your own Windows based desktop computers and there are no 3rd party services involved so you retain full control of the service as well as the costs. Even if you use web based configuration files or the delayed start feature, the file will be stored on your own website.



Will RemoteZilla work over a modem connection?

Yes it does, it's ultra-small AutoVNCsize k file download size and fast screen updates makes it the smallest and fastest solution available. Our goal is to get the code optimized even further in the near future.  Our nearest competitor's products are almost twice the download file sizes and RemoteZilla has more features and speed than competing products.



How do I setup port forwarding on my Firewall, NAT Router or Gateway?

Visit the website for the manufacturer of your device or go to and check out their impressive list of step-by-step instructions for various manufacturers of firewalls, routers, network address translators and broadband gateways as well as information on common ports, tricks & tips and more. 



How can I check my TCP ports to see if they are working?

Right-Click on the RemoteZilla viewer icon in the system tray (if you don't have RemoteZilla installed, Click HERE to download the RemoteZilla Port Tester) and select "Test Listening Port" to test your firewall, NAT Router or Gateway device port forwarding via the web. It uses your current IP address and the port the RemoteZilla viewer is listening on or you can manually specify a different port. If successful, the RemoteZilla Viewer will prompt you to accept an incoming connection. This does not establish an actual RemoteZilla connection but it will verify port is forwarding through to the RemoteZilla Viewer



How do I listen on port 443 and use Internet Information Services (IIS)?

By default, IIS binds to port 443 even when SSL isn't in use on the web
server. Here are two methods for changing bindings to the SSL port:
  • Install an SSL certificate, change the port value used in the Internet
    Services Manager, then remove the certificate.
  • Change the binding by using the Microsoft MetaEdit utility.

Contact us if you need more information.



Is RemoteZilla CPU intensive like other remote control software?

No, RemoteZilla requires very little resources.  Here is a screen capture of CPU usage captured remotely via RemoteZilla while RemoteZilla was in use on a remote system. This includes all the processes running on the system including the screen capture process itself.



Do I have to uninstall existing software to use RemoteZilla?

No, RemoteZilla can run on the same machine as an existing installation of other remote control software and can even be used to remote deploy, configure and install other remote-control software and setup and remotely configure hardware and software firewalls and NAT routers that would normally require on-site installation of other products.  It peacefully co-exists and can be run at the same time as other desktop sharing software including PC Anywhere, GoToMyPc, GotoAssist, WebEx, NetOp, RemotelyAnywhere, Microsoft Terminal Services, Desktop Sharing, RAdmin, TridiaVNC, UltraVNC, TightVNC, RealVNC etc. as long as they use different ports. 



Which RemoteZilla features can be customized?

RemoteZilla Executive, Corporate and enterprise Editions are designed for Corporations, Service Providers and VARS and is custom programmed with your company name, text, icons and logos to help protect your trade secrets from competitors.  RemoteZilla Corporate and Enterprise editions have all the customization options of the Executive Edition but can be customized even further to fit your corporate image needs. 

The level of customizing is up to you. For the basic customized package (AutoVNC-Advanced1 ) we will customize it with your own logos, icons, company name, contact info and your copyright embedded into the executable. The executable will still be named RemoteZilla.exe and the RemoteZilla name will still be displayed in the task manager task list and the Windows registry will have a RemoteZilla entry. This is the level most small to mid-sized corporations, consultants and service providers request.

If you require even further customizing, RemoteZilla Enterprise Edition replaces the RemoteZilla executable name and service name with the name you specify so that RemoteZilla is not displayed in the task manager task list, registry or executable etc... this costs AutoVNCenterprise (based on our standard hourly programming rate) but ensures you have a unique package that your competitors cannot easily trace back to Advantig as your supplier. This is the level of customizing most large corporations, VARs and ISP's request.



Can RemoteZilla be configured to allow inbound connections?

NO! Absolutely NOT, to do so would be a huge security risk!  RemoteZilla was designed from the ground up to increase security by specifically not allowing inbound connections as it serves no useful purpose since the server always connects outbound to the viewer and always re-connects if the connection is lost or the computer is rebooted. Unlike similar on-demand software, RemoteZilla does not allow inbound connections that hackers can exploit.  The customer cannot change the RemoteZilla server settings to allow inbound connections since there are none to change.  If you need to allow inbound connections, we recommend using VPN or installing a full featured remote control package with maximum security features enabled and change the passwords often.



Why are RemoteZilla prices so low compared to your competition?

RemoteZilla is only one of many products and services offered by Advantig so only a small percentage of our operating costs have to be passed to the RemoteZilla product/service line. RemoteZilla is a wholly owned product/service of Advantig and does not solicit nor accept outside investors. This allows us to determine policies to fulfill our customer's needs and requests quickly without outside investor pressure for higher profit margins. RemoteZilla is developed primarily for our own internal use and maintained in-house by our own programmers, not outsourced to 3rd parties which gives us additional motivation, savings and flexibility. 



Why is RemoteZilla so much smaller than other remote control software?

RemoteZilla is designed by us for our own technicians to support our own remote customers. It is optimized for speed and size using proprietary compilers and macro assemblers. We don't sub-contract or outsource RemoteZilla development, our full-time programmers work in-house alongside our own technicians and engineers so they understand the importance of small, fast remote support and make a team effort to keep the code as small and tight as possible. The RemoteZilla product you buy is the same RemoteZilla product our own technicians use. It takes more time to develop optimized code but the results are well worth the effort



Is the IBM OS/2 version of RemoteZilla still available?

No, IBM ended support for OS/2, all of our banking and retail customers switched to Windows 2000/XP or Linux and the demand for an OS/2 version was rare so December 31, 2001 we ended it's development. 



Is there a Linux/FreeBSD/Unix version of RemoteZilla available?

No, there is a Linux version of RemoteZilla in development and is currently in beta testing but no public release date has been projected.



What script or programming language does RemoteZilla use?

Unlike competing products, RemoteZilla is not script or batch file based and does not require using a batch file, winscript or setup installer to launch the program. It is a stand-alone executable program compiled from source code written in several different programming languages. The RemoteZilla server, viewer and remote installer is written in database driven Advantig Assembler v14.1 (*.asm) and Advantig C# Plus v14.2 (*.csp, *.c#p) cross-platform compiler (both were developed by Advantig for in-house development of storage limited devices). The RemoteZilla Repeater is written in Watcom C++/Fortran v11.0 (*.c). Other portions of the program (DSM encryption plug-in) are written in Microsoft Visual Studio .NET 2003 Enterprise Architect (*.c, *.cpp).
