was recently re-setting up my Windows 7 VPN server and forgot an essential step that led me to get ‘Error 720: A Connection to the remote computer could not be established' when http://www.paulkiddie.com/2011/06/a-fix-for-error-720-a-connection-to-the-remote-computer-could-not-be-established-when-trying-to-connect-to-a-windows-7-vpn/ trying to connect to it with Windows-based clients. Turns out you might need to http://xenomorph.net/windows/issues/dial-up-error-720-ppp/ assign an IP address range to the VPN server, by doing the following: 1. Go into Network and Sharing Center > Change Adapter Settings 2. Right click on Incoming Connection 3. Click on the Networking tab and double click on the ‘Internet Protocol Version 4 (TCP/IPv4)' checkbox4. Click the ‘Specify IP addresses' and type an IP dun error range that is in line with your current router setup (e.g. if your LAN is on a 192.168.11.x network, then you might want to set it as follows):You should now find, like me, that the VPN works once more! I'll post up a tutorial on how I got it working and accessible to the public Internet soon.Sharing:TwitterFacebookLinkedInGoogle +1RedditMoreEmailPinterestPrintStumbleUponDigg Tags: error, vpn, vpn server, windows 7 About Paul Kiddie .NET developer dun error 720 at thetrainline.com, previously web developer at MRM Meteorite.

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 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 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
