[mpich-discuss] Windows 7 64 problems with credentials (tried many things)

[Jim Hunziker]

I'm getting "Credentials for JAHWIN7\jhunziker rejected connecting to
jahwin7" messages in Windows 7 64-bit.

I installed the 64 bit version of 1.2.1p1, though I had the same problems
with the 32 bit version. The installation was done with msiexec /i
mpich2-1.2.1p1-win-x86-64.msi at an Administrator prompt. The installation
was done for "Everyone".

As a regular user (who does have a password), I ran mpiexec -register to get
my credentials in the registry. mpiexec -validate returns SUCCESS. I also
did this step as a newly created user, in case there was something weird
about my environment. The password is simple and alphanumeric.

When I use mpiexec to launch a program, it fails with the credential error.
If I look in the Windows Event Viewer, I can see a successful login has been
recorded.

If I run smpd -d to see the debug lines, there is an assertion failure in
smpd_affinitize.c on line 157. I believe this an unrelated bug because
mpiexec then fails with "op_read error on left context: Error = -1" rather
than the credentials error. Since this failure is related to process
affinity, I wonder if there's a problem relating to my using two processors
in my machine, which is a VirtualBox virtual machine.

Any help would be greatly appreciated.
