We are just now evaluating the use of mandatory profiles. Moving away from everyone having local profiles.
Can I ask how you have the local machine mandatory profile configured? Or better yet, confirm if I'm guessing at this correctly...
Configure a mandatory profile on a machine.
Deploy the mandatory profile during machine imaging
In AD for the user, specify the local path to the mandatory profile (ie: c:\users\default.v2)
Do you still use folder redirection to maintain user preferences?
Thanks for a great thread everyone... it's left me with a lot to think about.
