Hi,
Are there other 2070 events logged with different processes in the event viewer?
For example, Process Microsoft.Exchange.Directory.TopologyService.exe, Process MSExchangeMailboxAssistants.exe ,etc.
Do they have the same error code 0x34?
The problem may possibly result from temporary network issues between exchange servers and the domain controller.
