I can't figure this one out. Somebody, help! Okay, I'm trying to get this lady's PC to work. It had the Klez virus. Cleaned that out. But it has trouble connecting (dial up). Every single time I dial up, it dials, it handshakes, and then it says: "Error 720: A connection to the remote computer could not be established. You might need to change the network settings for this connection. For further assistance..." I tried a different modem, I tried a different ISP -- I even had an ISP admin come over to take a peak (we work together). I did a WinXP Repair (reinstall). Anyone out there have any ideas? Any help would be greatly appreciated.
