I am facing the problem in a Windows 2000 server(which is
not the domain contriller) it is a member server of a
domain and file server.
I am facing a problem while i want to add/change the
user's permission for a particular file or folder.
When I do the following:
1.Right Click on the folder.
2.Select on of "Sharing and Security" menu item.
3.Selection of "Permission" tab.
4.Clicking on the "Add" button
at this point I am getting the error:
"Unable to display the user selection dialog. (null)"
and I am totally unable to change any security options for
any of the folderthat server.
Any help me in this regarrg will be greatly appriciated.
