Modem disconnects AFTER it gets past verifying username and password

If the modem makes the handshake and gets past the "Verifying user name and Password" - i.e., it appears that you authenticate - THEN drops the connection, the problem may be a corrupt file in the connection, Dialup Networking, or the TCP/IP stack.

Error messages you may receive with this problem include:

[629/619] The port was disconnected by the remote machine

[628/678] The server is not responding. The computer you are dialing is not answering; try again later. PPP Modem Connect Failure

[650] The remote access server is not responding.

[718/635/691] Invalid username or password. Access denied because username and/or password is invalid on the domain. Remote Server could not authenticate the connection or Authentication Failed. Dial-up networking could not establish a connection; check your password and try again.

[720] Dial-Up Networking could not negotiate a compatible set of network protocols you specified in the Server Type settings. Check your network configuration in the Control Panel and try the connection again. No PPP Protocols configured.
