Can't get much better than the microsoft site
Once you create the user open it up.
Under profile
Profile path: \\admindc1\profiles$\roaming\isouthwell
Home folder: \\admindc1\isouthwell$
Under account
User login name: isouthwell
Where you create your roaming profile folder just make sure the user is in the security section, full control, and administrators, full control, otherwise you won't be able to access the folder from the server without taking control of the folder.
Under home drive, do the same on security but under sharing and permissions, add 'everyone' and full control. As the drive gets applied when the login no toerh user will be able to access that file.
Roaming profiles are fine on networked machines, it's wireless thats a bugger!
