Somehow there is something going on inside my pc I would really appreciate your help on this.... I use W2000 with Symantec AV + Sygate Firewall. At start-up Sygate reports "NT Kernel System has changed" with file identifier ntoskrnl.exe. Sygate asks whether that can access the internet and I say no. All seems fine but after five minutes or so IE denies I am connected. Mozilla the same. Outlook still runs as if nothing is the matter. Restart and the same happens again. I ran spybot-search and for good measure installed Spyware blaster. No use. I uninstalled about everything not essential. No use. There still is something weird going on... Any hint will help.
