Connection dropping 10 minutes after boot

[OceanView]

When I boot the machine, everything's fine. ping works, ipconfig reports
everthing ok, browsers work. ABout 10 minutes later, Page not founf on both
IE and Firefox...BUT...other connections still work, such as the xnews
browser I'm typing into now. Ping still works. When this started happening is
when I installed a require VPN software to connect to my employer's network.
I've since removed it, but the problem has stayed. I'm an old software guy,
but networks baffle me. What could be happening here and how do I find it?

Two things I've tried already: pare down the system to bare minumum and
installed the TCP connection limit removal patch (I was getting a warning
about that). Ideas?

If you have Zonealarm for a firewall, you need to mark the default internet
connection as trusted, (this applies only to always on connections) ie DSL or
cable, not dial ups.
else in ten minutes it does not get a DHCP refresh and times out.

You might have something there. I did have it installed and tried to
remove it, but had trouble. I think some of it is stills ticking it's nose
in.
