Mutex across network - C#.NET

Question

I have a message queue on a shared system. This queue is accessed by 2 processes which run on 2 other machines. I need to control access to this queue by the 2 processes. So I need a "network mutex". How can I achieve this?

I don't think this is supported out of the box in C#.NET but if I have missed something very obvious, do point me in the right direction. This question has been asked before but the solutions suggested involved a database. I dont have any database in question.

How To Mutex Across a Network?

Answer 1

You need a third process, which actually owns the queued items. The two workers each ask the third process for the next item, and it's this third process that polices access and acts as the lock.
