Exchange 2010: Cannot start cluster service.

When trying to restore Exchange in a two node mailbox cluster, you cannot achieve quorum.

The alternate witness seemed to get corrupted.

  1. Disable DAG AD computer account
  2. Run cmdlet New-Cluster -Name DAG01 -Node SVR-MBX04 -StaticAddress -NoStorage.
  3. Run cmdlet Start-DatabaseAvailabilityGroup -Identity DAG01 -MailboxServer SVR-MBX04


Get-DatabaseAvailabilityGroup DAG01 -Status | FL

lists StoppedDatabaseServers and StartedMailboxServer correctly.
