Thanks so much for your timely and detailed help. Sorry that I became involved in other issues today and my reply is delayed.<br><br>1. I removed mpich2 completely and reinstalled, and rebooted between and after these operations (as every superstitious windows-user has learned to do when problems occur). I installed for everyone, as I have done previously.<br>
<br>2. mpiexec -validate simply prints the statement "FAIL"<br><br>3. I followed your directions for smpd and mpiexec in debug/verbose mode. Log files are attached.<br><br>I will continue to play with this; thanks again for your continued help. My intuition is that this problem has to do with my having both renamed the machine and my user account just prior to setting this up a few days ago (to make the user accounts the same on both machines and make the machine-name less unwieldy to type). But every other test I have performed to check the validity of the new names passes.<br>

<div></div>The test command suggested (mpiexec -n 2 hostname) works fine on
one of the machines. On the other machine (both are winXP) I get the
error:<br><br>Credentials for thomas rejected connecting to mb13<br>Aborting:
Unable to connect to mb13<br><br>This is the result of just running locally,

<br><br>I wonder if this has to do with my having changed the machine name on

wmpiregister and entered my username and password (which I use to login to

[mpich-discuss] mpich2 1.0.8 on windows - domain
required?<br></font><br></div>
<div>
<div></div>
<div>
<div></div>Hello,<br><br>I have just subscribed to the list to ask a
question about mpich2 on windows. (I found the archives but don't see
a way to search them).<br><br>Is it a requirement that the windows computers
participating in mpich2 be part of a windows domain? I see things in
the documentation that perhaps imply this, but not state it
outright.<br><br>My computers are simply on a local network, and part of a
"workgroup". The smpd process manager can "see" the other systems to
some extent, since the result of<br><br>smpd -status mb13
// mb13 is the hostname of my other windows pc<br><br>correctly finds that
smpd is running on my other host. But executing mpiexec and providing
hostnames in a "machinefile" e.g.<br><br>mpiexec -n 4 -machinefile machines
echo %COMPUTERNAME%<br><br>fails with:<br><br>Credentials for thomas
rejected connecting to mb13<br><br><br>I have taken care that the
username/pass is identical on each machine, the user is admin, etc. I
have followed steps I've found in various documents about
uninstalling/installing smpd and providing the identical passphrase on each,
running mpiexec -register, etc...<br><br>Any ideas? (Or is it just
that I must be running on a domain, which I cannot find concrete
documentation about)<br><br>thanks very much, <br>thomas blom in austin,
tx<br></div></div></div></blockquote></div><br></div></div></div></blockquote></div><br></div></div></div>
