Hi,
 I would recommend uninstalling MPICH2 and installing it again from the administrator command prompt by following the steps below.

# Download the latest version of MPICH2 (http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads).
# Open an administrator command prompt (Right-click on the command prompt icon and select "Run as administrator")
# From the admin command prompt use the msiexec utility to uninstall MPICH2 (eg: Type "msiexec /x mpich2-1.2.1p1-win-ia32.msi" to uninstall MPICH2 using the mpich2-1.2.1p1-win-ia32.msi installer)
# The above command will bring up the Installer GUI to uninstall MPICH2. Follow the steps to uninstall MPICH2.
# From the admin 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.

Regards,
Jayesh

Hi, Very thanks for your response.
I sorry, I now open an administrative command prompt.
Now, when I write:
smpd -start
I have the output:
OpenService failed:
El servicio especificado no existe como servicio instalado (error 1060).

When I write:
smpd -install
I have the output:
MPICH Process Manager, Argonne National Lab installed.

Now, I write:
smpd -start
I have the output:
MPICH Process Manager, Argonne National Lab failed to start.
Ya se está ejecutando una instancia de este servicio (error 1056)

And when I write:
smpd -status
I have the output:
Please specify an authentication passphrase for smpd:
I write the authentication passphrase and the system response to me:
Aborting: unable to connect to User-PC

And when I write:
mpiexec -n 2 hostname
I have the output:
Please specify an authentication passphrase for smpd:
I write the authentication passphrase and the system response to me:
Aborting: unable to connect to User-PC

I will thanks any help.
