Customer was trying to create a private queue on a Windows 2008 R2 Server and getting back an "insufficient resources to perform this operation" error when trying to create a private queue.
It has been 5+years since I have worked on a MSMQ Insufficient Resource to perform this Operation error. On Windows 2000 and 2003 these errors were pretty frequent and the root cause was due to storage size. So when I got this customer reporting this on Windows 2008 R2 Server I was a little surprised since storage size is not a really that big of a deal.
After a little digging around, I found that the security on the server had been hardened. As a result of this, the MSMQ storage directory default security had been modified and had locked the msmq service out and the service was unable to access the storage folder.
We gave everyone group full access to the msmq storage and that resolved the issue.
