Hi,
 The error message shows that you did not specify an authentication passphrase for SMPD. If the installation process was successful you should not be seeing this message.
 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.

Regards,
Jayesh

Hi, Very thanks for your response.
I reinstalled the MPICH2 by the steps that you say to me.
After the installation I try to run a non-MPI program (mpiexec -n 2
hostname) and I have the same error:
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
Very thanks.
I will thanks any help.

>> Hi,
>>  This is strange. From the error messages it looks like you don't have admin privileges. Are you able to open an administrative command prompt (Right-click on command prompt icon - select "Run as administrator")?
>>  What is the output when you type "smpd -install" from the admin command prompt (You have to run the command from an administrator command prompt)?
