My sql service is started using local system and agent and redgate start waitforsingleobject with a domain user. I have tried using 2 different domain accounts but still the same error as below SQL Backup Agent startup error: error initialising IPC objects. Error creating mutex (already exists): Global\\SQBMutex_ The SQL Backup Agent service terminated with service-specific error 5000 (0x1388). One of the users i was trying to start had a different error SQL Backup Agent startup error: error initialising IPC objects.

Could you be so kind to share the solution? Thank you, Jason Jdubs Posts: 1Joined: Thu Sep 07, 2006 7:53 pm Top by petey » Thu Sep 07, 2006 11:59 pm What I suggested was to download Process Explorer from sysinternals, to find out who owns SQBMutex_. By them, the user was eventually able to restart the service, which implied that the object was somehow orphaned (perhaps due to an incorrect shutdown) and Windows had eventually cleaned it up.
