Mandatory profiles

Penfold

We use mandatory profiles a lot in work and these are configured by renaming the .dat to .man. However whilst studying for the 70-294 I read that you can either use the above method or set the group policy 'prevent roaming profile changes from propagating to the server' so whats the diff?

This GPO setting allows you make and save changes to the profile locally, but those changes will not be propagated to the server and downloaded at the next machine you log on to. Since the settings are not uploaded, they won't be downloaded and merged the next time you log on to the same machine.

Looks like it would be useful if you regularly log on to different types of machines with different applications. No more broken application shortcuts or a huge desktop full of files following you around everywhere, but you can still make changes locally.
