I applied SP5 to a NW6.5 server running on a Dell Poweredge server.
After restarting it I applied the updated post SP5 server.exe and NSS
patches. When I restarted the server it got as far as replaying the
transaction log and abended. Since I applied two patched at the same I
am not sure which one broke the server. I am guessing the NSS patch did
it since it was trying to mount volumes when it crashed. I did a down
server upgrade to repair it and then applied SP3 and the post SP3
server.exe and NSS updates. That worked properly and the server is now
up and running. Is there a known issue with SP5 post service packs? It
would be nice to know for the future.
