[mpich-discuss] Problem using Mpich2 on Vista machines

[Fairchild, Jack]

Thanks for the quick response Larry.  Windows fire wall is off.  I can ping the machines, and can access the machines through explorer.  The pass phrases are all the same "behappy" and since it's all networked, my login and passwords are the same.  Just in case, I did run the smpd -register command to no avail.  We're attempting to work around the problem now by cloning one of the working hard drives.

Jack,

Try the firewall first, you have to unblock the smpd service port.  Beyond that, you have to verify that smpd service is installed,  and if it's another host, you will either have to register a pass phrase, or your account on the execution node to be able to continue.  If your password ever changes, you have to re-perform this step.

I've debugged as far as I can:

Invoking the command: mpiexec -validate -host myhost  returns:
Aborting: connection to smpd rejected

Invoking mpiexec -file myfile  returns:
Aborting: unable to connect to myhost

Some background.

All computers are running Vista Ultimate.  The computers are connected by a 100mbs LAN.  A few months ago, I set up 4 machines for this use.  They all still connect without issue.
At this point I need to add some more, but am getting these errors.  All machines have smpd version 1.0.8.  I am an administrator on all machines, and installed Mpich2 as the administrator.  UAC was turned off and remains off, all known firewalls are also off.  A path variable to the bin directory  was added.

I ran smpd -d and all of the parameters match those of the working computers.

What am I missing here?  I appreciate your valuable time.
