XADM: Directory Service Terminates Unexpectedly with Event IDs 1186, 1229, and 1171

• Microsoft Exchange Server, versions 4.0, 5.0

SYMPTOMS

The Microsoft Exchange Directory (DS) may terminate unexpectedly with the following sequence of events in the Windows NT Event Viewer:

   Event ID: 1186
   Source: MSExchangeDS
   Type: Error
   Category: Replication
   Description: The internal directory replication agent (DRA) Dispatcher
   thread is waiting in a remote procedure call (RPC) to directory
   XXXX. The directory has attempted to cancel the call and
   recover the thread, with status 0x0.  If this condition
   persists, stop and restart that Microsoft Exchange Server
   computer. 

   Event ID:1229
   Source: MSExchangeDS
   Type: Warning
   Category: Replication
   Description: The remote procedure call (RPC) which was being executed by
   the internal directory replication agent (DRA) Dispatcher thread has
   been canceled.

   Event ID:1171
   Source: MSExchangeDS
   Type: Error
   Category: Internal Processing
   Description: Exception c0000005 has occurred with parameters 603049ac
   and 0(Internal ID 10c009b). Please contact Microsoft Product Support
   Services for assistance. 

CAUSE

The event is logged because a thread is stuck (hung) in RPC. The DS uses a global pointer for the name of the server last replicated to. But the pointer we are looking at does not match the current global.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 4.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 4.0.
