2601, 2604, and 2501 MSExchange ADAccess Event IDs

Hallo zusammen,

Tauchen auf einem Server mit Exchange 2010 im Application Log die EventIDs 2601, 2604, and 2501 von der Source  "MSExchange ADAccess" auf, dann gibt’s folgenden Microsoft Knowledgebase Artikel dazu http://support.microsoft.com/kb/2025528

The causes of this lookup failure include, but are not limited to, the following:

  • Transient DNS failures
  • Transient issues with Domain Controllers
  • Transient network connectivity issues
  • Network switches that have the PortFast functionality disabled on the ports to which the Exchange servers connect
