DPM protection agent service may stop responding on Exchange Server 2010 servers that are protected by System Center DPM 2010

Applies to: Exchange Server 2010 EnterpriseExchange Server 2010 Standard

Symptoms


Assume that you use a Microsoft System Center Data Protection Manager (DPM) 2010 server to protect Exchange Server 2010 servers. However, the DPM protection agent service on the protected Exchange Server 2010 servers may stop responding. Additionally, the DPM 2010 server cannot communicate with the Exchange Server 2010 servers. Therefore, the DPM protection agent does not finish performing a backup of the Exchange Server 2010 servers.
