I am running sbs 2003 standard edition and laterly I have had a problem with active sync
copied from event log (application)
Event Type: Error
Event Source: Server ActiveSync
Event Category: None
Event ID: 3012
An error occurred while accessing the Active Directory for user [Internet Guest Account]. Information cannot be retrieved from Active Directory due to an unknown error. Verify that the Exchange ActiveSync Server can communicate with Active Directory, and that the user has a valid account.
For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp
I have tried googling but not getting anywhere.
Also I look after the IT here parttime so I am not that technical.
Thanks in advance
