When you run the Windows 2000 SP3 Terminal Services client Setup program, you receive:
Conman.exe - Unable To Locate DLL
The dynamic link library TSCTRC.dll could not be found in the specified path <PATH>
If you press OK, the installation completes, but running the Terminal Services connection manager (Conman.exe) causes the error to be re-displayed.
To workaround this feature, copy %SystemRoot%\system32\clients\tsclient\net\win32\TSCTRC.dll to "%SYSTEMDRIVE%\Program Files\Terminal Services Client\TSCTRC.dll".
Conman.exe will now start correctly.
