RE: Exchange 2007 Active Sync not working for one of my AD sites

Since the issue is with authentication, see if you have any ADAccess errors in the event log on that Exchange server. Also, run "repadmin /showreps" from the command line on the DC that is local to that Exchange server and verify that replication is healthy between the DCs at different sites.
