Hi jlokecke ,
Have you tried Window Winsock XP Fix ?
Have a nice day.
If the above does not work, then I would try refreshing the TCP/IP Networking Stack by going to Dial-Up and Networking, right click on your connection icon select properties, uncheck everything in the box hit apply (noting what was there), then reboot then proceed reinstalling the items in that window.
You can also try upgrading your network card drivers,
If the above doesn't work then I would start to suspect malware.
