help lost my network connection

Hi, I ran crap cleaner on my win2k system earlier, then rebooted, but
now I have lost my internet connection, and networking. The win2k
machine now can't see the other win98 machine, which could about an hour
ago, and vice versa. I can't ping the other machine, and yet the tcp/ip
addresses are still there.
Another problem which has occured is that both firefox and thunderbird
will now not load up.

What can I do to get it working again?
help please
Thanks

Update here, it was my firewall which sort of got screwed and stopped
all outgoing connections
