Hello everyone,
I'm seeing quite alot of unusual behaviour at the moment. We're using SCCM 2012 SP1 CU1 with a CAS and Primary Site for demonstration purposes.
When adding a Computer to an Installation Collection, I can deploy a Task Sequence to that Collection, fire up the Computer via USB Boot Medium and kick of the OSD, which completes successfully. NO Unknow Computer support is activated! Neither is PXE!
When I try to run the OSD on the same machine again, the OSD fails with the message, that no Task Sequence is available. Nothing will work, until I've deleted the Computer from SCCM and reimported it.
I've read the this behaviour could be to an GUID not being unique, but I've tested that by creating a Collection and having a query add all systems with GUID "xyz"... only one system in the collection.
I have absolutly no idea why this is happening and I've never seen this behaviour before. Any ideas?
Cheers,
Fred
