I am using Biztalk 2006R2, I have NOT used MSMQ.
But I found that there is a mqsvc.exe running in the Biztalk server, what is the usage of mqsvc.exe in Biztalk environment?
This is Microsoft's Message Queueing Service (MSMQ), if I were you, I would leave that service alone, as it was most definitely installed for a purpose in that environment. Here's an article for more details:
