I have a nw6.5 sp5 server. I was having trouble with backup exec showing
disconnected with the tape drive. Veritas suggested the Proliant Service
Pack to update the drivers. I installed the SP and rebooted the server.
The server would hang when booted. I went through the loadstage process
from 1-4. Upon executing autoexec, it stops loading at SPXS.NLM. On the
logger screen, I see the error for NLAP not being able to load and the need
to run tckeygen.

Would certificate problems cause a server to hang while loading?
