I’ve gone as far as importing the entire Security Template from Vista in my Server 2008 test machine with no success either. I’ve also been looking at an alternative to MCE called Origami which seems awfully cool itself. I’ll leave my comments null for now since this topic is based on MCE only.
I’ve also looked into the possiblity of different versions of core DLL files between Vista Ultimate and Server 2k8. I haven’t found that isn’t the same version yet which relates to MCE. I’ve been monitoring the EhShell.exe with PROCMON and Process Explorer utilities too. So many threads are initiated by this EXE, it’s a bit hard to track the exact root cause still.
I’m throwing my best at it tho! Cheers.
