Level:         Error Description: Process MSEXCHANGEADTOPOLOGY (PID=1276).

Log Name:      Application
Source:        MSExchange ADAccess
Event ID:      2501
Level:         Error Description: Process MSEXCHANGEADTOPOLOGY (PID=1276). The site monitor API was unable to verify the site name for this Exchange computer – Call=DsctxGetContext Error code=8007077f. Make sure that Exchange server is correctly registered on the DNS server.

Solution – 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. Depending of the role of the server it may cause a service disruption due to dependent services having to restart as well.
