I installed Win 2000 Pro SP4 on my PC. I installed Zone Alarm 5.5 something. After installing and configuring whenever the OS started it started hanging. I have P3 800MHz with 320 mB RAM.
What should I do???
Please update your system with windows update has even sp4 is not full and a lot of critical updates are required to patch.. and also consult MS / Zone Alaram Customer Service
Boot in Safe mode . uninstal Zone Alarm . Then boot normally . Try some other Firewall since some versions of ZoneAlarm has issue with windows 200 SP4 up.
You may also try ZA other recent version or the free version they have .
