NIS 2009 stopped running, unseen in systems tray, no notice it had stopped (never does that for me anyway). When trying to use the start>programs>NIS 2009 (to start it), a 'help' (ha!) like window opened and said I needed to uninstall & reinstall NIS 2009 (Ya, right, like that ever did anything but get the damned thing to run for a few more weeks or months).
Googled this thing and only found 'others in 2008', who saw this error (8404, 4) and who followed Symantec's advice, while could uninstall & reinstall, still had an issue with NIS running with any other user on the OS. That was enough for me to realize following Symantec/Norton advice was NOT the thing to rely on.
Here's what worked for me (and no, it had absolutely nothing to do with what Symantec recommends).
Brief opinion and history -
Confident that Symantec 'fishes' for support $'s and ignores and/or supports a NIS 2009 bug that causes NIS 2009 not to startup at times, when I myself found NIS 2009 not starting up recently, seemingly associated with (at shutdowns) a popup saying ccSvcHst was running, was closing, wouldn't, so I end tasked it, another same popup, did same end task and then OS would shutdown.
Tried the Symantec recommendation to run msconfig, hiding MS services in services tab, then unticking all remaining services and then in startup tab do somehting or other, and re-boot. Didn't do squat (NIS 2009 still wouldn't start up).
My solution -
I began my shutdown process, choosing to end task the ccSvcHst popups (which I suspect was/is Symantec's aspect of the bug trying to make sure it NIS 2009 won't startup at next startup), then during re-boot, I pressed F8 and opted for the 'load drivers' (something like that), let it list all the loading drivers, it auto re-booted and presto, NIS 2009 started up (finally listed in systems tray).
I'll be highly surprised if Symantec/Norton moderators allow this post (loses 'forced' support $, just my opinion).
