To put it mildly, the Altiris SMP 7.1 MP1's DS suite is not looking good. And if you have a working DS 6.x, do not migrate to DS 7.x!
Especially if you came from a previous DS 6.x back ground. The pxe now named SBS is flakier than the combo's at Long John Silvers, and the UI design is as simple as solving the Super Strings theory.
So the facts:
PXE works, but it does strange stuff at times and the only way to resume functions when a machine refused to function within PXE is to Stop all SBS services and clear out the Task Handler folder.
PC join domain, naming. Mother of all nightmares. How this could be such a complicated set of dance moves is shocking. This is an Enterprise product?
PC cant be re-named in WinPE, so the randomized name gets used as the PC name after the jobs at times.
Here is to a good productive day on resolving the PC join domain after imaging issues. But it's future is bleak based on what we are seeing now.
