Thanks for the reply, one thing I have noticed is an app error in the event log
How do I disable offline caching (as usual with MS not that helpful a log), is there a way to do this in GP. It may not be a cause of the above problem but it another one crossed off the list.

Userenv event 1525 may appear in the application event log:
Event Type: Warning
Event Source: Userenv
Event Category: None
Event ID: 1525
Time: 3:42:11 PM
Windows has detected that Offline Caching is enabled on the Roaming Profile share - to avoid potential profile corruption, Offline Caching must be disabled on shares where roaming user profiles are stored.
For more information, see Help and Support Center at http://support.microsoft.com.
This event may occur if the following conditions exist:• A Windows XP-based computer is member of a Microsoft Windows NT 4.0-based domain or of a Microsoft Windows 2000-based domain.
• You put the roaming profile of a domain user on a Windows NT 4.0-based server.
• You log on as this user from a Windows XP-based computer.
The warning is recorded in the log to notify the administrator that it is possible for the client to cache files from that share. Although you cannot set caching on Windows NT 4.0-based shares, Client Side Caching (CSC) interprets the lack of caching options as manual caching. Therefore, as far as CSC is concerned, the Windows NT 4.0-based share is cacheable. This can permit profiles to be cached. The warning notifies administrators of this issue.
