I have a customer that is having issues with their Unity 4.2 system. It is a VM only system with Exchange on-box. The issue is that the Message Queuing Service fails to start automatically, and cannot be started manually. They are getting an error in the Windows Event Viewer (Application) that states that the Message Queuing Service failed to initialize. Nothing has changed on the system, and no updates have been applied, yet they have this symptom. Obviously, since the Message Queuing Service fails to start, several of the Unity services also fail to start due to their dependancies. What could be causing this? And, more importantly, how can this be resolved?
Thank you for your time and assistance,
I've seen this happen many times before... cause really isn't known. Most cases involved a re-installation of Message Queueing. Rarely is it resolved otherwise. This usually requires you to have the OS disc, so have that handy just in case. You can remove and re-add it from Add/Remove Windows Components.
I would also recommend just as a safe-guard to have a good backup of Unity prior.
Hope this helps, if so please rate.
