User powered down station after uneventful day and next morning was no longer able to print. All printers were deleted and NT will error when you try to add a new printer with, "Operation could not be completed. The RPC server is unavailable".
The spool service no longer starts up automatically and will generate the following error if you try and manually start it, "Could not start the spooler service on \\Computer Name. Error 1067: The process terminated unexpectedly".
SPOOLSS.EXE generates, "Exception access violation (0xc0000005), address 0x7543171e

The RPC configurator has been removed and reinstalled along with SP5 without change.
Any help would be greatly appreciated.
