Recently, one of our server was completed with inplace upgrade from Windows 2000 to 2003. After the upgrade, when you right-click My Computer icon in the Desktop and choose Properties, the Remote tab was missing. Because of this I was unable to configure remote desktop settings and this was fixed by registering the DLL file using the below command.
regsvr32 %systemroot%\system32\remotepg.dll
If you receive an error stating that the module could not be found, or stating no registration helper is registered for this file type (which indicates a corrupt DLL), extracting a new copy from the installation CD should help.
To extract the DLL from Windows the installation CD, type this in Command Prompt
EXPAND X:\I386\REMOTEPG.DL_ -R C:\WINDOWS\SYSTEM32
Note: considering X is you CD ROM and C as your Windows drive.
Thanks,
