How can I configure NT Server 4.0 to not allow users to login if their mandatory is not available?

Start User Manager for Domains on the PDC

Select the User and click the Profile button

Check the users "User Profile Path"

Start Explorer and move to the users path and select his folder, press F2 (to rename) and just add .man to the end of the folder name, e.g. savillj.man and hit enter

Back in User Manager add the .man to the profile path, e.g.
\savillj.man

Close User Manager for domains
