Remote Administrator FAQ

Yes.

This option enables you to connect through a host when there is no direct TCP/IP connection with the computer you want to administer, but an intermediate computer (or host) has a direct TCP/IP connection to your target computer running Radmin server.

Therefore Radmin server must be running on that intermediate (host) computer as well as on your target computer. Ex: You have a local network without a direct connection to the Internet. However there is one computer on that network that has a direct connection with the Internet.

If you install Radmin server in the that computer, the host, you will be able to get connected from the Internet to other computers in the local network.

If you want to send Ctrl-Alt-Del key to a remote computer you can use 'Send Ctrl-Alt-Del' entry from the Remote Screen window menu.

This feature will work only when the remote computer OS is WindowsNT and the Radmin server runs as a system service on the remote computer. This feature will work in 'Full control' connection type.

Just press F12. Using this key you can switch between normal and full- screen modes. if you want to send the F12 key to a remote computer, use 'Send F12' entry from the RScreen window menu.

Radmin currently supports DHCP on a network with DNS only.

To speed up, you can disable wallpaper on the remote computer. Also, make sure, that the 'Strict to 256 colors' checkbox is checked in the Options dialog of the RScreen window.

If you are connected via a modem you can't have update rates higher than 10 per second, just because signals can't go there and back more than 10 times per second (ping > 100ms).

If you use Win95/98 OS on the remote side, the speed depends on the screen resolution of the remote computer. So set a lower screen resolution on the remote computer. Also set a lower color format 8bpp (256 colors) or 16bpp (65536 colors). On some systems 8bpp is faster, on others 16bpp.

Make sure your update speed is not limited by the 'Maximum updates per second' field from the option dialog of the RScreen window. If you use WinNT on the remote side without the video hook driver installed, note that with the video hook driver Radmin works about 10 times faster and uses much less processor time.

Also, if you obtain a high processor load on the remote computer, when you see its screen remotely you can make it lower by setting the 'max screen updates per second' entry to a smaller value in the 'Options' dialog of the RScreen window menu.

If your remote computer works under Win95/98/ME/2000 (or under WinNT without the video hook driver installed) the Radmin server can cause a high processor load when the 'Maximum updates per second' value is set to values bigger than 50. Anyway Radmin takes only free CPU, so it's not causing a performance hit.

Currently, Radmin can't register screen changes, when the remote computer is in the full-screen text mode.

Drawing on the screen isn't performed by the GDI (Graphic Display Interface) when the remote computer is in such a mode. Windows works with full-screen text modes in an undocumented way via a video port driver.

Some Win32 console applications use direct access to the console. Such applications can't work via the telnet mode, because the telnet mode on the server uses standard i\o streams to interact with the application.

Just do not run such applications via telnet. You can run such applications in RScreen mode.

This error usually means that connection is broken by the server side due to IP filter restriction on the server. To see and change your IP filter settings, you can run 'Radmin server setup' (Remote Administrator Server Setup) from the Start menu on the server side. If you get the message "Can't connect to server" you can turn on the log file to know the reason. Perhaps, RServer does not start.

Be sure that you have the same versions installed on all sides. The problem can be also caused by some other software that may be incompatible with Radmin. Another possible cause is the network problems, be sure you can ping the remote PC.
