Lync Server 2010 Monitoring role setup components fails with: “Prerequisite not satisfied: Message Queuing Server (MSMQ) and Message Queuing Directory Service Integration must be installed before attempting to install this product. MSMQ must not be in workgroup operation mode.”

I was recently asked to look at a problem someone had running the Setup or Remove Lync Server Components step when setting up a Lync Server 2010 Monitoring server.

As the wizard begins to setup the monitoring server components, it would fail when checking the MSMQ prerequisite:

MSMQ must not be in workgroup operation mode.

I’ve never ran into this error before when I was asked about this but from reading the message, it looked like there was something wrong with the MSMQ service.  I asked if the service was installed and was told it was done a while ago.  Since I knew installing the MSMQ service for Lync wasn’t as simple as just selecting the Messaging Queuing node (you had to expand it to select Directory Service Integration):

… I went ahead and checked the features:

As shown in the screenshot above, the Directory Service Integration checkbox was indeed unchecked.  To get past the error, proceed with the following:

1. Installing the Directory Service Integration component.
2. Restarting the server.

What was interesting was that we were not asked to reboot the server when the installation of the Directory Service Integration component completed but when we ran the component setup again, it would fail with the same error.

Hope this helps anyone out there that may have missed that component.
