I just Tried running the MP.MSI on the target server and got the following error Dialog Box during setup:
Setup Failed due to unexpected ciercumstances
The error code is 80004005
and:
Setup encountered an error and will not continue,
Same error as is being reported in the MPSETUP.LOG
This morning I uninstalled IIS, Deleted all SMS registry entries, reinstalled IIS rebooted, and ran setup (from CD files on Targed Server) on the server again with the same results, I'm not ever sure what to try next at this point.
