I am using windows 7 professional 64bit. I have created a new user to allow an XP machine to connect using user names and passwords. When I go to share a directory, the sharing wizard of windows 7 shows the user in the dropdown list to add a user, but when it is selected, it gives an error of "Windows cannot find "user name". Only seems to happen for some users, while others are ok. Any ideas ... currently a critical issue to get a production server connected. Server user name is SNHSE-1.
