MPI only works when connected to remote hosts via RDP

Hello, I am experiencing an issue where MPI only executes the work on remote hosts when I am connected via RPD to those hosts.

I have a large processing job which has been split into parcels and farmed out to hosts. I can see from the log files generated by each host and written back to my central repository (mapped drive passed with the -mapall switch) that the hosts receive the instructions but then appear to stall. If I stop the job, connect to the hosts via RDP and then restart the job the hosts will happily process away.

From what I have read the MPI authentication is closely connected to RPD but it appears to be more than an authentication problem as I have added the -login switch to force me to authenticate and it doesn't make a difference.

Does anyone have a suggestion as to how to I can identify the issue?

Regards
Ian
