[mpich-discuss] Credentials Rejected - Windows Vista/7 Home Premium

[Leonard E Schwer]

Thanks again Jayesh for the reply.

I attempted your suggestion to -validate and this failed:


C:\Windows\system32>mpiexec -remove
DeleteCurrentPasswordRegistryEntry:RegDeleteValue(password) failed, error: 6
ERROR: Unable to remove the encrypted password.

C:\Windows\system32>mpiexec -register
account (domain\user) [SECS8\Schwer]:
password:
confirm password:
Password encrypted into the Registry.

C:\Windows\system32>mpiexec -validate
FAIL

C:\Windows\system32>hostname
SECS8


I *think* SECS8 is both the hostname and computer name, but is at least the hostname.

Hi,
 After registering your username try validating the username/password with the "-validate" option and provide us with the results.
 Is "SECS8" the domain name or the computer name (Type "hostname" at the command prompt) ?

Regards,
Jayesh

Thanks Jayesh for the response.

I have installed the 64-bit version of MPICH2 on the Windows Vista & 7 boxes.

Yes "Schwer" is a user on domain "SECS8," with admin privileges. 

I believe I demonstrated in my original email the your suggestions, re: -remove & -register. Also, accepting the offered domain/username via hitting a return and then supplying the password.

Thanks again for your offered suggestions.		--len

Hi,
 If you are installing MPICH2 on a 64-bit machine we recommend that you install the 64-bit version of MPICH2 (http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads). Try if it works.
 From the error message, It looks like the username/password combination is not valid.
 Is "Schwer" a domain user (on domain SECS8)? Try accepting the default username (Press Enter key when prompted for the username with the "-register" option) and provide the password when prompted and see if it works.
 Let us know the results.

Regards,
Jayesh

Hello --

I have a successful Windows XP 32 bit install of MPICH2.

I have attempted installs on two other boxes: Windows Vista and Windows 7,
both 64 bit. As far as I can tell the install went well.

My problem is getting either install to recognize my username/password.

Below is a command window session where the command window was launched
using "Run as Administrator"


C:\Windows\system32>mpiexec -remove
Account and password removed from the Registry.

C:\Windows\system32>mpiexec -register
account (domain\user) [SECS8\Schwer]:
password:
confirm password:
Password encrypted into the Registry.

C:\Windows\system32>mpiexec -n 1 hostname
Credentials for SECS8\Schwer rejected connecting to SECS8
Aborting: Unable to connect to SECS8

Any suggestions or pointers?

Thanks,	--len
