<div>Hi Ondrej,</div>
<div> </div>
<div>I have had this behaviour on 2 occasions with XP and 1.0.8:</div>
<div> </div>
<div>1) Router interference from a second network router prevented validation or any other MPI comms. Switching 2nd router off and using only 1 router solved problem.</div>
<div>2) Nothing but nothing helped and I fiddled my guts out and received some good advice. So installed Vista on 2nd partition and booted into that for MPI work. Worked a charm.</div>
<div> </div>
<div>Regards, bob</div>

I was able to get over the validation of mpiexec (mpiexec -validate returned SUCCESS). Anyway, if I want to run even the simplest program possible,i.e. mpiexec -host second_host hostname, I always get the error:<br><br>Credentials for Ondrej rejected connecting to shrek<br>
Aborting: Unable to connect to shrek<br><br>(Ondrej is the name of first computer, shrek is the name of second). If I do "smpd -status shrek" (from Ondrej computer), I get:<br><br>smpd running on shrek<br><br>So it seems that everything is ok. I turned off the firewalls, I can ping each other and also the shared folders are accessible from both computers. Just the mpi is not running as it should. I reinstalled mpich2 and rebooted computer so many times, that it couldn't be reinstalled and rebooted any more. Does anyone have some similar problems or at least have any clue how to solve this? Thanks.<br>
