Domino 9.0.1 FP5 finally installed, but "nsdhelp.dll" was missing afterwards ...
The news flash from IBM also stated that you could rerun any hotfix-installers to revert back to the previous level of code. I found my HF419 installer and ran it again. First it identified that I could revert back to vanilla 9.0.1 FP4 level, and I continued... First off I got this:
... hmmm, for some reason the updater didn’t finish off the running nsd.exe, so I had to do that manually via the Windows Task Manager. Re-ran the code and now it finished with success
Time to re-run the FP5 updater, and this time it correctly identified the 9.0.1 FP4 code and let me finish with success.
However, on a re-start of the Domino server, it couldn’t start due to a missing nsdhelp.dll file;
Bummer!! I couldn’t find it anywhere on my server, so I had to restore it from my backup!!
The last sign of nsdhelp.dll is in the UPGRADE.LOG and it seems like the HF419 renamed it:
Rename: canFileName: nsdhelp.dll, dw = 9
Temp file size was 0: UPTMP0009.TMP
Seems like the FP5 updater went a tad too fast through the quality control this time. Normally I would say that upgrading the server has been a breeze over the last years. Just download the updater, run it, and voila ... the server is updated.
