Drop-Outs with Socks

Using Vista Ultimate, I have a home network with 3 PCs. One PC keeps
intermittently dropping out-going connections. It happens with IE during
uploads but more noticeably with a program like Skype. I have tried
resetting tcp/ip with no help. I completely uninstalled the Norton firewall
with their Removal program and no help. Is there anyway to re-install Socks?
Any other ideas about the possible cause for uplink drop-outs?
Thanks...!

Sorry, I meant winsock not socks (a proxy).

I have tried a winsock catalog reset and tcp/ip stack reset to no avail.
Any ideas appreciated!
