I've lost my registration code. What should I do?
Answers to Frequently Asked QuestionsWhat does the error message "Connection .. was rejected because of license restriction" mean?
It means that the program has found the fact of infringement of the license.
For example, the registration code allows you to use the program only on two different computers. Earlier you were connected to these computers using the Admin Module and now you are trying to connect to another computer. In that case the program shows the message about infringement of the license. Also such message may appear when the license has not been violated, but some hardware on the remote PC was changed. In this case you must reenter the registration code in the Admin Module (Menu/Help/Enter registration code). After that you will be able to connect another remote PC.

Why do I see a blank screen while remote PC in full screen DOS mode?
It happens because the current version of Remote Desktop Controlcannot work with full screen text modes. However you can press Alt+Enter combination to switch the remote computer to the windowed text mode.
Note: You can send keystrokes to the remote host, only if you are working with the remote computer in "Control Mode"
Go top
Why the remote screen sometimes looks so ugly?
Sometimes while viewing the remote screen, it may look ugly. It happens when you are using a color depth of 8 bit per pixel. In this case we recommend you to use the color depth of 16 bits per pixel or more. You can change the color depth in the system menu of the Remote Screen Window (press Ctrl+F12).
Go top
How can I speed up the program's performance?
In case of a poor performance of Remote Desktop Controlwhile viewing of the remote screen, it is recommended (in order from most effective remedy to less effective):
On the Host site:
Use better video adapter (with many video memory) and latest video drivers.
Reduce color depth and screen resolution.
Remove wall-paper from the desktop.
Use "Security Level 1" option in the Host Configurator settings (note: this is not recommend when the high security of network connections is required).
On the Admin Module:
Use "auto" color depth in Remote Screen Window for LAN connections and "8 bit per pixel" for slow internet connections. Use the system menu (Ctrl+F12) to change Color Depth.
Also we recommend to use 100 Mb and more network adapters to improve network performance.
Go top
How safe is Remote Desktop Control to use?
Remote Desktop Controlis a secure remote control program. It has a large number of security features that can be used to defend PC from unauthorized remote access. Here are some reasons Remote Desktop Controlis completely safe:
Access to the remote computer is restricted by password. A challenge-response authentication of connections is provided for prevention of unauthorized access to computers with the working Remote Desktop ControlHost program (the program uses digital signature algorithm RSA with a private key of 320 bit length).
Remote Desktop Control works in encrypted mode. All data streams, including screenshots, keystrokes and mouse movement are encrypted by a symmetric, randomly generated key of 64 bit length that is given to the both sides during the process of authentication.
IP-Filtering feature allows an access to the Remote Desktop ControlHost only from specified IP addresses and subnets.
Master Key usage guarantees a safe storage of the Access Passwords for connection to the remote hosts on the computer with Remote Desktop ControlAdmin (it is used strong encryption with 256-bit key).

I don't find the answer. How to contact your support team?
The technical and customer support are managed by our R&D Department in Ukraine (GMT+2 Time Zone). Please be patient if there is some time difference with your current location.
For any technical questions, bug reports, comments or request please contact us via web form.
When contacting support team please specify:
Remote Desktop Controlversion and Windows version on the Admin and Host PCs.
The problem you faced and all other information that you think is related to the problem.
If you have problems with connection, please describe your network environment:
Where host and admin PCs are located (in the LAN or Internet), which type of IP addresses they have (private or public). Describe intermediate points located between PCs, such as proxys, routers, firewalls, etc.
Go top
How to update all copies of program to the new version?
At the first, you should download the newest version of software from our web site:
www.remote-desktop-control.com
After that you can install a new version of Remote Desktop Control on your computers.
If you want to update Remote Desktop Controlon a different computer(s) in your LAN, the computer has to have an access to the installation package (via LAN for example). In this case you will be able to update Remote Desktop Controlon each PC separately by launching the installation program.
You will receive notifications about updates automatically, if you are a subscriber of our mail list or a registered user.
Go top
How can I send Ctrl-Alt-Del combination to the remote PC?
You can send Ctrl+Alt+Del combination to the remote computer in "Control Mode" only. Also the Host Module must run as a system service on that remote PC. Press Ctrl+Alt+F12 or call the system menu of the Remote Screen Window and choose menu item "Send Keystroke > Ctrl-Alt-Del".
Go top
How to hide the tray icon of the Host Module?
Run the Host Configurator program from the Programs menu. Select "Launching" page and then select the "Hide tray icon" option.
Go top
How to transfer files to or from a remote PC?
Current version of Remote Desktop Control does not contain this feature, but we will include this feature into the new versions of Remote Desktop Control.
Go top
How to prevent a closing of Host Module?
A tray menu of the Host Module contains the "Exit" command to close the Host Module. Actually the user of remote computer should not be able to shutdown the Host Module, because the network administrator needs to have a stable access to the remote host at any time. It is recommended to hide the tray icon on each workstation. The administrator can do this using the Host Configurator program (see Launching tab).
The Host Configurator program also contains the "Close Host Module now" button, which allows you to close the Host Module when the tray icon is invisible. Therefore, you should protect this ability with password; see the Security tab of Host Configurator.
For Windows NT/2000/XP/2003:
If you are using the Host Module as a simple application, the computer user will be able to shutdown it using the Task Manager. You should use the Host Module as a system service if you want to avoid this issue. Only users with administrator's privileges will be able to stop the service through the Service Manager.
Go top
How can I switch "Full-Screen" mode to "Windowed" mode?
Use F12 key for switching between "Full-Screen" and "Windowed" modes. if you want to send the F12 key to a remote PC, use 'Send Keystroke / F12' entry from the system menu of the Remote Screen Window.
Go top
How to determine which remote computer I'm controlling now?
In the "Windowed" display mode look at the title of Remote Screen Window, you will see the remote computer's display name.
In the "Full-Screen" display mode, you should temporary switch to the "Windowed" mode (F12), and look at the title window.

How to copy the Remote Desktop Control address book from one computer to another?
The address book is stored in the apc-addressBook.ini file in the work folder of Remote Desktop Control. You can simply copy this file to another computer.
Go top
Why can't I connect to the remote Host?
The reason can be different. For example:
You have incorrectly entered a port number or IP-address/name of the remote Host
The Host Module is not running on the remote PC.
The remote computer is switched off or its network cable is disconnected.
The firewall protection on the remote host is used.
There is no direct TCP/IP connection with target computer (computers is located in different network for example).
You can test a connection to the remote computer using a Ping command in the system console: ping [remote_host]
Example:
ping 10.0.0.1
ping myserver.mycompany.com
Go top
How to determine the IP address of my computer?
Every computer connected to the Internet or network is assigned a unique number known as an IP address. There are many ways to know the own IP address, we recommend following:
Move your mouse pointer over the Host Module tray icon. The tool tip will show the list of IP addresses.
Type ipconfig (winipcfg for Win95) command in the system console.
Go top
How to control a remote computer from the network station via internet?
At the first, you should know IP-address of the remote PC. Also you need to have an access to the remote PC via TCP/IP from your local network. For accessing the internet from local computers we recommend to use the server with two network interfaces: internal (local network) and external (Internet). Operation system of this server doesn't matter. There are many variants of server configuration:
The server works as a gateway, providing a shared Internet access to multiple PC's or other devices. In this case Remote Desktop Controlcan simply be connected to the remote host using the IP-address.
If your server works under Windows2000/XP/2003, you can use ICS (Internet Connection Sharing) on your server for granting internet access to computers of your local network:
www.microsoft.com/WindowsXP/pro/using/howto/networking/ics.asp
You can use NAT (Network Address Translation) on your server for granting internet access to computers in your local network.
NAT is a program that converts the IP address from a private address to a public one real time. This allows multiple users to share a single public IP address. It also prevents access to these users from the outside without special configurations. NAT is used in home networks and corporations to allow multiple PCs to access the internet via T-1, ADSL, SDSL or Cable Modem.
Read more...
If your server runs under Windows 95/98/NT, we recommend you to use Kerio WinRoute as NAT software.
It is possible, when HTTP Proxy (for example Squid or WinRoute) is used for granting the internet access to computers located in your local network. The current version of Remote Desktop Controldoes not work through HTTP Proxy servers. This opportunity will appear only in the following versions of the program. However there is a way of connection to the remote computers through a HTTP Proxy. It is HTTP-tuneling.
For realization of this opportunity you can use special software, for example: HTTPort or Socks2HTTP
These programs allow you to bypass an HTTP proxy, which is blocking you from the Internet. With HTTPort you may use the following software from behind an HTTP proxy: Remote Desktop Control, IRC, ICQ, FTP, etc.

How to control a remote PC through the firewall?
Remote Desktop Controluses TCP port 6279 by default. You can open this port on the firewall. Another solution is to change the Remote Desktop Controlport number on both sides (for Host Module and Admin Module) to the value of a port that is already opened on your firewall. 80 or 21 for example.
Go top
How to control PC with dynamically assigned IP address via internet?
You can connect to the remote computer via Internet. The only problem might be the IP address on the Host Module side. It could be dynamically assigned; therefore you should find out it after the remote PC connection to the Internet. Someone on the remote side could tell you the remote IP address by phone or email for example. After that you connect to the remote computer using known IP address.
If you are often compelled to be connected to the remote computer with the dynamically assigned IP-address, and nobody on the remote side can tell you a current IP, you can use some of services, such as www.no-ip.com. It will help you to know the IP address of the remote Host even if it often changes.
Go top
How to control a network PC via internet?
It is possible when computers are located in the internal network behind a NAT based router. In that case computers have no public IP addresses, i.e. addresses are private (192.168.x.x for example); and only a router has a public IP address (211.27.164.21 for example).
You need to configure "Forwarding" on the router/firewall to control internal network computers from the Internet. You should configure the router to forward connections from a port on the router to a specific IP address and port of the target computer in your internal network. It is necessary to assign unique port on the router for every computer you need to control.
Remote Desktop Controluses TCP port 6279 by default.
How "port forwarding" works? Terminology:
Port on the network PC is a private port. Network PC is private.
Port on the router is a public port. Router is public.
Router should forward traffic from its different public ports to different private computers
