I get the following error whilst attempting to (re)load windows XPP Sub-component COM+ raised an exception while processing the OC_COMPLETE_INSTALLATION setup message. d:\nt\com1x\src\complussetup\comsetup\csetuputil.cpp [line 3406] Error code = 0x8007007f The specified procedure could not be found. Failed to load the library 'C:\WINDOWS\system32\catsrv.dll'. Why am I reloading XPP - HISTORY: PC failed to boot up becomming hung at the blue "welcome to Windows screen" From bios it appeared one of my 2 Raptors in a RAID 0 array had failed. Reloaded XPP. Attemtped to configure router but it would not recognise ethernet connection (previously happly connected via ethernet) and had to be hooked to USB. Many random crashes. Apparently device driver related although unable to find which. Finally it is booting up to the desktop but immediately shutting down and rebooting - this in a never ending cycle. Attempted windows "repair" through the XP installation disk - see above error message! Any ideas?
