Why does MSMQ think I'm on a workgroup computer?

Question

My computer is connected to a domain, but when I go to create a public queue:

MessageQueue.Create(@\".\\testqueue\");

I get this error:

Answer 1

Being part of a domain is a pre-cursor for installing MSMQ in AD-integrated mode. It doesn't guarantee MSMQ IS installed in AD-integrated mode. MSMQ will install in workgroup mode if:

1. AD integration was not selected as a setup option
2. AD integration was selected but failed to initialise; check event logs

Yes, the workgroup name is confusing in a domain member situation.
