Web connection dropping shortly after boot

[OceanView]

Hi guys,

This has me stumped. 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?

Is it Cisco VPN?
