tcp/ip

Hi,

Since upgrading from XP Home to XP Professional, which I did so I could connect to my College network, the tcp/ip on my laptop doesn’t work and my Administrator is suggesting I rebuild my laptop, which I consider to be a dire option.

Whilst my laptop can apparently ‘connect’ via wireless to other networks Explorer works as if it’s offline. It can be pinged, on occasion but can’t ping out to the College server.

Any advice including cheaper and less dramatic options out there?

Thanks, John.
