I have Windows 2000 Pro installed on a computer.
It has been running without problem. It has Norton
Anti-virus installed on it. Virus defs are up-to-date
and a full system scan came back clean. Real time
file system protection is enabled.

I installed Spybot search & destroy. Updated the defs
and cleaned things out.

I defragged the hard disk. I ensured no additional programs
are starting up.

Nothing I have been able to do has helped the recent lag
that its expriencing. Slow application start ups, slow access
(or not at all) to external websites. There has been NO change
to the system. Operating fine, then boom. Lag.

Any ideas ?

Just a thought,but have you thought about disabling startup items that you don't need to start on bootup.Having too much stuff in there can slow your system down dramatically.The only things I allow to start on bootup on my machine are my anti virus and firewall.

and check out the service configurations,there are a lot of services that you can disable to help your system run better and faster
