I have just started playin' with the Webservice and integration with SCCM.
My Lab setup:
Windows Server 2003 with IIS 6
SCCM 2007 SP2 (Beta)
Everything is working almost perfect.
I can access (and write to) the MDT database, so that part is working.
But when I was trying to get something from SCCM, I ran into trouble. (f.ex. "GetTaskSequences").
There wasn't any TaskSequences listed.
After playing around for a while, I tried to change "DefaultAppPool" - "Identity" from "Network Service" to "Local System".
And then everything works perfect. So obviously something with permissions.
But should'nt it work with "Network Service" ... ??
I tried to look in the "WMI Service" -> "SMS" - "Security" but that did'nt solve anything.
So obviously I'm missing something somewhere... ;-)
