<P><FONT SIZE=2>I have tried all these. It appears to be related to the win2008 domain controller. Has it been tested in this config?<BR>

Hi,<BR>
Can you run hostname without specifying "-hosts" (mpiexec -delegate -n 1 hostname) ? Also make sure that you are running mpiexec using delegation from a node with SMPD Service registered (Run "mpiexec -delegate -n 1 hostname" from a node where you executed "smpd -register_spn").<BR>
Did you get any errors when registering SMPD Service Principal Name (smpd -register_spn)? Try removing the principal name and registering it again to verify (smpd -remove_spn ; smpd -register_spn).<BR>
<BR>

<BR>
All,<BR>
<BR>
I have attempted to get MPICH2 1.08 and 1.1 to work on Windows and receive the following error when performing the following command:<BR>
<BR>
C:\Program Files\MPICH2\bin>mpiexec -delegate -hosts 1 central2.itlab.platform.com hostname<BR>
<BR>
GetGC failed 0x1<BR>
<BR>
DsMakeSpn(mpich2_smpd, central2.itlab.platform.com, 8676) failed: The parameter is incorrect.<BR>
<BR>
unable to lookup the smpd Service Principal Name.<BR>
<BR>
unable to initialize an sspi context command.<BR>
<BR>
mpiexec aborting job...<BR>
<BR>
C:\Program Files\MPICH2\bin><BR>
<BR>
I am absolutely certain that I installed smpd using the following command, and it was successful.<BR>
<BR>
smpd –register_spn<BR>
<BR>
Any help would be appreciated.<BR>
<BR>
