Hi, Very thanks for your response!!!
I does not have error messages during MPICH2 installation. I turn off
the firewall for run mpiexec -n 2 hostname.

The output of "smpd -status" from an administrative command prompt is:
no smpd running on User-PC

I try running mpiexec -n 2 hostname from the administrative command
prompt and I have the same error:
Error while connectig to host, No se puede establecer una conexión ya
que el equipo de destino denegó expresamente dicha conexión (10061)
Connect on sock(host=User-PC, port=8676) failed, exhaused all end
points Unable to connect to 'User-PC:8678', sock error: Error = -1

Very thanks. I will thanks any help.

>> Hi,
>>  Did you get any errors during the installation of MPICH2 ?
>>  I would recommend the following,
>>
>> # Uninstall MPICH2 from your system.
>> # Download the latest version of MPICH2 (http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads).
>> # Open an administrative command prompt (Right-click on the command prompt icon and select "Run as administrator")
>> # From the administrative command prompt use the msiexec utility to install MPICH2 (eg: Type "msiexec /i mpich2-1.2.1p1-win-ia32.msi" to install MPICH2 using the mpich2-1.2.1p1-win-ia32.msi installer)
>> # The above command will bring up the Installer GUI to install MPICH2. Follow the installer steps to install MPICH2.
>> # After the installation try to run a non-MPI program (mpiexec -n 2 hostname) . If the job launcher, mpiexec, requests for a username/password please provide the same (When specifying the username/password make sure that you specify the domain name if the user is a domain user).
>>
>>  Let us know the results.
