Server with NW 6.5 SP6 abended.

Now, if we reboot the server and let it "auto-load" portal.nlm it will
keep abending.

I REM'd out portal.nlm and then booted up just fine.

If I then try to load portal.nlm manually I get an INIT FAILED and the
logger screen shows:

Error starting Built-In services, ccode = 0xFF
Server-5.70-1553: Module initialization failed.
Module PORTAL.NLM NOT loaded

Any ideas?
