Comment: For Exchange servers running Windows Server 2008 R2, these event IDs (2601, 2604, 2501) are caused by Exchange not re-trying AD query after initial failure. Per MS KB2025528:
"After the server has been up for a minute or two, run NLTest /DSGetSite to verify that that the proper Active Directory Site is being returned by Windows.  Once that has been verified, restart the MSExchange ADTopology Service." Index: 9243
