<P><FONT SIZE=2>Its likely around security model. If you look at how delegation works, on a per host basis, it has changed dramatically.<BR>
<BR>
The constraining of services used to be available through the registry and the available authentication types I don't believe existed.<BR>
<BR>
That's why my guess is authentication. However, the function binds and then searches, which is working, but only by name.<BR>
<BR>
Looks like your on it though.<BR>

Hi,<BR>
DsMakeSpn() is called with a NULL ServiceName and according to the MSDN docs the ServiceName should be non-NULL (As you mentioned in your prev email this could be something that has changed over time).<BR>
GetGCSearch() fails with error "ERROR_INVALID_FUNCTION"... Interesting...<BR>
<BR>

Sorry for the delay. Register spn works fine and nothing works relative to delegation in 2008 HPC. From the service principal perspective, we are able to see the service principal registered in Active Directory just fine after running the command.<BR>
<BR>
Please keep in mind that AD in 2008 has changed quite a bit relative to service principals. There are now several additional options, and my guess is that the API has changed as well.<BR>
<BR>
If you take a close look at the error messages from your code, you will see the following:<BR>
<BR>
GetGC failed 0x1<BR>
<BR>
DsMakeSpn(mpich2_smpd, central2.itlab.platform.com, 8676) failed: The parameter is incorrect.<BR>
<BR>
So, we need to understand what GetGC is and why it failed, and then cascading to the DsMakeSpn.<BR>

Hi,<BR>
Can you run hostname without specifying "-hosts" (mpiexec -delegate -n<BR>
1<BR>
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>

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>
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>

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