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

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

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

I get this error:

A workgroup installation computer does not support the operation.

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

I know this is late, and there is already an accepted answer, but I just had this issue and it was resolved by changing the format of the queue string.

When my queue name was this, I got the workgroup error:

".\QueueName"

When I changed it to a more formal version, there was no error and sending to the queue worked:

"FormatName:DIRECT=OS:ComputerName\private$\QueueName"

Just in case someone else comes across this post, now they have something else to try...
