I have set up a PC to act as a server at home and have installed Norton Internet Security 2007. The PC then took to stopping anything from 1 to 5 times day. Looking at the reports in Event Viewer, I noted that the stops always appeared to be related to NIS going online for some sort of update. On the Symantec website, I found a note that they had had reports that NIS automatic liveupdate could cause systems to stop. However, Symantec had not been able to reproduce the fault and there was 'no solution'. They recommended a workround of turning off automatic liveupdate. I did this, but found that the automatic liveupdate service was still running, so I opened the service, stopped it and changed its status from automatic to disabled. The PC was then fully stable, no stops at all.
However, if I reboot, the automatic liveupdate service is mysteriously reset to automatic and started, presumably by NIS, and so my PC again has the problem of these occasional stops, until I open the automatic liveupdate service, stop it and disable it.
Does anyone know of any action I can take either to prevent automatic liveupdate from stopping the PC in the first place, or alternatively how can I stop NIS from resetting it on reboot?
