We use roaming profiles for certain users. In the LAN environment it seems to work fine. When the profiles are instead placed on a fileserver on the WAN we've had many issues. The fileserver is reachable with <50ms ping so I don't know that it's a timeout issue. The fileserver and path seem good using the UNC name. The primary error is seen at logout "Your roaming profile failed to synchronize complete."
Any ideas for what to check on this one?
Edit: I should add the clients with issues are windows 7 pro x64.
