We are running a W2K8 Domain with roaming profiles. Users profiles are directed via group policy to a DFS share \\company.lan\files\profiles\%username%. When my laptop users (Win 7 x 64) are connected to the LAN all is well. When they leave my network they cannot logon. (User profile service failed the logon). I am sure this is because the profiles.v2 folder is not cached properly. I have enabled offline files for the userprofile share, and the .v2 share. I notice when the user returns to the LAN and logs on after an unsucessful offline attempt the profiles.v2 folder no longer displays as offline, however the profiles folder (no V2) still has an offline indicator beside it. I assume this is my problem. Any help is greatly appreciated.

If the domain user is out of the site, the logged on sessions cannot pass the user authentication. How Interactive Logon Works http://technet.microsoft.com/en-us/library/cc780332(WS.10).aspx You need to save the credentials for the logged on users and allow users to log on with the cached credentials. Additionally, although the user profile folders are available offline, you still need to load the profiles from the server when log on. The offline folders are not equal to local folders. To resolve this issue I suggest you change the profile to local domain profiles. If you log on offline, the loaded profile should be the cached profile that was saved at after your last logon.

My clients require roaming profiles, they log onto multiple machines and need to keep certain profile data with them. This concept worked with roaming profiles prior to Win 7 and Svr 2008. It still works on my XP clients in the 2008 domain.
