Mutex problem

I have a problem with Mutex.

I start a program with a spezific mutex / Mutexname. I only know the mutexname from this program. This program has to be started from different PCs with different program names.

Now I have a second program for maintenance that have to check if the first one is open.

If the first one is open, the second program have to perform a specific action.

I checked the existence with

Mutex.OpenExisting(mutexname)

This forks fine.

Now my problem. How can I get information about handle or program name from the first program when I only know the mutex name in the second program.

I hope some of you can help me.

Best regards

Matthias
