connection, it went like this: - Modem would pick up the phone and dial. - Carrier sounds / handshaking would occur. - Username and password were checked and verified. - Then it would disconnect with an error error 720 code of "720" More on the message: Error 720 - the connection attempt failed because your computer and the remote computer could not agree on PPP control protocol. I had tried every fix I could find. Removing the Winsock error 720 a and Winsock2 keys, re-installing TCP/IP, and running a series of commands using the "netsh" tool. None of that worked. What seemed to work: "WAN Miniport (IP)" seemed to be messed up some how. It was listed twice in Device Manager. I had to remove the keys for the two entries from the registry, then I could remove the devices from Device Manager. I had to use the "devcon" command to re-install the "WAN Miniport (IP)" device. The command to restore the WAN Miniport (IP) device was: devcon.exe install %windir%\inf\netrasa.inf MS_NdisWanIp You can get DEVCON.EXE (32-bit and 64-bit) from here: http://support.microsoft.com/kb/311272/ You can get more info on this from here: http://www.daniweb.com/forums/thread18016.html Home Log in Copyright © 1999-2016 XdN
