I'm doing a upgrade on my NetWare 6.5 sp2 box moving it to sp3. After the reboot I get the following error in loading of Stage 1

Loader Cannot find public symbol: RegisterNSSFlusAPIs for module NSS.NLM

It isn't loading NSS.NLM so I can't continue the boot process at all. I haven't a clue what to do.

please does anyone know? Server is down its the Primary DNS server, I have the backup going, but I need to get this back up and running.
