James,

There is no mention about username or password in OMPI. I guess one of the applications used in the process, either the ssh or the ipconfig.exe is missing the current context to be executed without a higher level of credentials.

Can you execute ipconfig.exe once connected through ssh without having to provide the username and password? If yes, can you execute hostname through mpirun instead of ipconfig.exe?

If saving credentials is not selected, then I can see that the task starts on the other machine (in task manager) and that the task runs to completion OK:
