Thank you very much for your reply. After sending the mail i experimented some and came up with the following solution:

In "Documents and Setting" i looked into the "Start Menu" of the other user and saw no Windows Messanger shortcut in the "Programs" folder

But there was a shortcut in the "Start Menu" of my folder and the "All User" folder

I just copied the shortcut from my folder to the users "Program" forder in the "Start Menu" and wallah.....the user can open messanger now.

By the way I opened the GPedit but how do u give permisiions to a particular user?

Thanks again
