Dear Computer solutionist in the house, how do i solve the error 633 in modem dial up using the Windows XP and Windows Vista O/S. This error occurs if you are a using a dial up modem to connect to the internet. When you boot up your system initially, your dial up modem (whether bluetooth or cable) connects very okay, but when you disconnects the connection and try to connect again, it displays that Error 633 issue. The only way it could connect again is to restart the system, but i dont want to do that always. I tried several thing, but it did't work. Please, what is the best and final solution to resolve this issue.

Stop using the dial up method to connect to the internet(it can very unreliable). This can be disable from Tools>>Internet option on internet explorer. Enable "NIC for data connection on your modem interface. That should solve the problem
