Windows Server 2003 internet connection problem [resolved]

Hi,

A few days ago my server installed a Windows Update (it was a Service Pack update, I wasn't really paying attention to which number).
Anyway, the following day my server won't connect to the internet. I'm guessing that the Windows Update perhaps changed a setting that I am unaware of. Since I know very little about servers I'm a bit nervous to change things in case I make everything worse.

Anyone got any ideas?

Thanks

I uninstalled utorrent, restarted the machine and everything is ok now. I've no idea why this fixed the problem, but I'm happy anyway .
