<P><FONT SIZE=2>Hi,<BR>

<BR>

&gt;&gt;.. I launch mpiexec.exe from an another windows user acount...<BR>

<BR>

&nbsp;This could be your problem. You can try registering a username/password available on both the machines using the &quot;-user&quot; option (mpiexec -register -user 1) &amp; launch your job using that user (mpiexec -n 2 -user 1 -hosts 2 10.0.0.10 10.0.0.13 hostname). You can also validate if the user credentials are capable of launching a job using the &quot;-validate&quot; option of mpiexec (mpiexec -validate -user 1 10.0.0.10 ; mpiexec -validate -user 1 10.0.0.13)<BR>

<BR>

(PS: Did you copy-paste the complete output of the mpiexec command &amp; the command itself ? Please don't remove any part of the output. This will help us in debugging your problem.)<BR>

I have registered with wmpiregister.exe the same user with the same password on both computers but I launch mpiexec.exe from an another windows user acount; could this be a problem?. Thanks<BR>
