Error 720 A Connection To The Remote Computer Could Not Be Established
running Windows 7 RC and have a PPTP VPN connectoid that connects to a Server 2003 RRAS server. I was able to successfully connect just yesterday but today when I attempt to connect it gets as far as "Registering your computer on the network" and then fails with Error: 720 "A connection to the remote computer might not be established. You might need to error 720 a connection to the remote computer cannot be established windows 8 change the network settings for this connection." *sigh* I always hate it when things that worked one day suddenly and with seemingly no reason stop working. To my knowledge no updates have been applied to the server or to my Windows 7 machine in the time between yesterday and today. First I check to see if my Virtual XP instance can connect to the VPN. I created a new VPN connectoid and was able to connect with no problems using simple default settings. I then looked at my Windows 7 connectoid's options and did a little twiddling like disabling "include Windows logon domain" (not sure how that got enabled in the first place) and moved it from PPTP to Automatic (all it does is delay the logon time while it tries to figure out how to connect from among the available options but I figured it was worth a try). Still no luck. I created a brand new connectoid using the default values for everything and it still gave me Erorr: 720. Fortunately I have a secondary VPN that I use for just such an occasion. It's via a SonicWAL

connection from my laptop to connect to other networks. This has worked fine for some time, but now all workplace related connections do not work anymore. http://thenubbyadmin.com/2010/09/12/solving-pptp-vpn-error-720-on-windows-7/ When I start such a connection, I get this message: Err=720 (A connection to the remote computer could not be established. You might need to change the network settings for this connection. Nothing has been changed in the connections itself. First it worked, now it doesn't. The only difference is that I https://social.technet.microsoft.com/Forums/windows/en-US/3a60b643-dbbf-4aad-b3dc-d817c7075701/vpn-connections-stopped-working-error-720?forum=w8itpronetworking recently uninstalled "Cisco Systems VPN Client 5.0.07.0440". I needed this package for another VPN connection but uninstalled it due to BSOD's it was causing when I tried to start a workplace VPN connection. I tried several things in order to solve the issue, all without success: * Re-installation of "Cisco Systems VPN Client 5.0.07.0440"; * Reset TCP/IP stack using netsh; * Removing the WAN Miniport (L2TP) device from registry and hardware manager; <-- one of the problematic workplace VPN's use this * Disabling the "Microsoft Kernel Debug Network Adapter"; Does anybody have any ideas?

I do not think this is an issue with the set up of the VPN as it works for all other users. I have tried disabling windows firewall and disabling Zone Alarm anti Virus. The laptop is a 64-bit running windows 8. Any suggestions or help would be greatly appreciated as I cannot see why this error 720 a will not work. windows-8 vpn share|improve this question edited Nov 28 '15 at 18:00 DavidPostill 58.3k18118148 asked Jun 17 '14 at 14:01 Albert 18117 Have you tried using ping to the VPN server from the computer? –10100111001 Jul 26 '15 at 5:14 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote I've had loads of issues recently creating VPN's in Windows 8 (or at least my users creating VPN's) due Windows 8 not propagating the security settings whatsoever. Click the network (monitor or wireless signal) icon in the bottom-right of the screen Right-click your new VPN connection and select View connection properties In the dialogue box, click the security tab, under Type of VPN select Point to Point Tunneling Protocol (PPTP) Select the radio button Allow these protocols, then tick Challenge Handshake Authentication Protocol (CHAP) and Microsoft CHAP version 2 (MSCHAP v2) and click OK Try again and see if this has fixed the issue. share|improve this answer answered Jun 17 '14 at 14:10 CharlesH 1,6882516 Unfortunately I do not think this would make any difference, the VPN is set up to use Layer 2 Tunneling Protocol with IPsec (L2TP/IPSec). So I suspect changing this would cause even more issues. –Albert Jun 17 '14 at 14:28 Ah fair enough that one already set then yeah? Windows 8 caused us loads of headaches not automatically populating these settings with the defaults. Can you make sure IKE and AuthIP IPsec Keying Modul
