<P><FONT SIZE=2>Hi,<BR>
Did you install MPICH2 as the administrator ? If so, did you specify that MPICH2 is to be used by all users (The default is "Just me", you need to select "Everyone" when installing MPICH2) ? Try re-installing MPICH2 making sure that you install MPICH2 for all users (Select "Everyone" when prompted for while installing MPICH2).<BR>
<BR>
(PS: Since the problem does not appear to be a bug we can discuss your issue in the mpich-discuss mailing list. If we feel there is a bug in the code we can re-open the ticket 717.)<BR>

Hi,<BR>
<BR>
EXCUSE ME! My English Is Very Low Level. EXCUSE ME!<BR>
<BR>
I do this jobs that you said:<BR>
<BR>
# Make sure you have the same user (reza) on both the machines and that they have the same password (Assuming reza is not a domain user).<BR>
# Register your username/password using "-register" option of mpiexec WITHOUT the "-user" option (mpiexec -register).<BR>
# Run your MPI jobs WITHOUT the "-user" option (mpiexec -n 2 cpi.exe)<BR>
# Use wmpiconfig if needed.<BR>
<BR>
But it errored me!<BR>
<BR>
Error is it " Credentials for reza rejected connecting to PC1<BR>
Aborting: Unable to connect to PC1 "<BR>
<BR>
At first time I want to perform this statement "mpiexec -n 2 cpi.exe" it errored!<BR>
But after I perform this statement "mpiexec -user 1 -n 2 cpi.exe"<BR>
username:administrator<BR>
password:administrator password.<BR>
the cpi is runing!<BR>
<BR>
After Performing above statement I do this job:<BR>
<BR>
I type this statement : "mpiexec -n 2 cpi.exe"<BR>
mpi not errored and running the cpi.exe!</FONT>
