...or not. SP4 seems to have either caused, or catalyzed, a problem in our SYS: volume on a homebrew server. Calling Novell to help figure it out. "invalid super block headers" is the magic key, and none of the TID's are helping. And modules from NW6NSS3c aren't working either. Next step is to try and move files from the backup (thankfully saved to a traditional volume) to the C:\NWSERVER directory and see if we can get up THEN. As this server is our ArcServe backup server, rebuilding will be a !$~%!@#.
