how many users? I wonder if NSPI limits have been hit on your DC
KB17325-NSPI connection limits when using a Microsoft Windows Server 2008 Global Catalog Server - NSPI Bind Limit exceeded

is the user started? check you MAGT MDAT logs

we have around 75 domain users and about 25 on bes.

[knottyrope]

and did you check the BES logs?

Also cant hurt to do a permissions test on the users account too
