SYMPTOMS
The Microsoft Message Queuing (MSMQ) Service may take 20 minutes or more to start up on a Domain Controller (DC) with hundreds of sites and subnets.



CAUSE
When MSMQ starts, and then by default every hour after startup, the MSMQ Directory Service creates an association list between subnets and Active Directory (AD) site globally unique identifiers (GUIDs). However, the site GUID is not stored in the AD; only the site’s Distinguished Name is stored in the AD. As a result, the MSMQ Directory Service must execute a query to obtain each site’s GUID for every subnet.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
