I installed ESS4 on an XP SP3 system. As soon as it finished installing it popped up to say it had detected a couple of bad files. The messages didn't stay on the screen, but I believe one filename was wsock3.dll. It asked to reboot and I said sure, why not. After reboot I got a little triangle-exclamation over the network icon in the tray, and I didn't have any connectivity. I tried to right-click and Repair, but the message was "Windows cannot finish... Renewing your IP address'. I followed the FAQ about disabling certain IDS elements, but that didn't help. I appreciate getting rid of a bad file but I'd rather not throw my Internet connection out along with it . What to do??
