Odd error..
Usually this means there is a windows problem, either with your connectoid (your dial up networking connection) or 'buggered' up drivers for your modem..


Windows might of also messed up your modem drivers, uninstalling, reboot, and reinstalling your modem might help as well (using your original modem drivers disk), and updating the drivers with the newest if possible.

If the problem persists.. ask yourself this question, "Did this start after I installed anything, or there were any windows changes", if so, that could of caused this.. Also, "Are their any other windows errors/problems which appear unrelated with this error that also plague this PC" If so.. bigger issue with windows then just fixing your connection to your isp/internet...
