Hi, very thanks for your response.
I created a new user called MPI and I reinstalled the MPICH2 only for
this user, and I executed the sentences that you say for me.
When I write
smpd -uninstall
The system response to me:
Stopping MPICH2 Process Manager, Argonne National Lab.
MPICH2 Process Manager, Argonne National Lab stopped.
MPICH2 Process Manager, Argonne National Lab removed.

When I write:
smpd -install -phrase behappy
 The system response to me:
MPICH2 Process Manager, Argonne National Lab installed.

When I write:
smpd -status
 The system response to me:
smpd running on User-PC

When I write:
mpiexec -n 2 hostname
 The system response to me:
User credentials needed to launch processes:
account(domain\user) [User-PC\MPI]:

And at this point I does not how I should write, I try with MPI or
User-PC\MPI, but does not work.
Then the system ask to me for the password:
I write the password that I use for the MPI user, and the system response to me:
Credentials for MPI rejected connecting to User-PC.
Aborting: Unable to connect to User-PC
I think this is because I does not known how I should write when the
system ask to me:
User credentials needed to launch processes:
account(domain\user) [User-PC\MPI]:

I will thanks any help.

>>>  During the installation process, the MPICH2 installer requests for the SMPD passphrase. A default SMPD passphrase is provided in the user input textbox for convenience. Did you delete/remove the default passphrase during the installation step ?
>>>  Can you reply with details the steps used to install MPICH2 (You can add inputs to the installation steps that I provided in my previous email)? Also specify, in detail, if you modified any default input values during the installation process.
