Error 721 Vpn Windows Xp
in eventvwr are coming up during the process of failing. Firewall is also off on both the computer and router. VPN pass through is enabled on the Linksys router. Just for troubleshooting purposes I have enabled DMZ for the IP of this computer so all ports are open. Any other ideas of whats going on?

However sure enough it was enabled when I decided to check it again.

I have FINALLY resolved an ongoing issue with our VPN connections that we have been experiencing for over a year now. I will share these findings with this error 721 directv forum in case others can benefit from our situation. First let me explain the problem. The Problem: It can take up 6 retries for any remote user to successfully created a remote PPTP connection to our servers. Whenever we try to connect it display the following message: Verifying username and password... And it sit there displaying this message for about 30-40 seconds, then it says: "error: 721 https://social.technet.microsoft.com/Forums/office/en-US/bf4a482f-3f91-43a1-8e57-2029bf508d84/windows-xp-pro-sp3-vpn-error-721?forum=itproxpsp The remote computer did not respond." Network Setup: We have two netopia routers on our network. They both have their own separate WAN connection (we use a lot of bandwidth, hence the need for two WAN connections). One RAS server is configured to use one router as it's gateway, and the other RAS server uses the second router as it's gateway. When PPTP connections are made, the connection http://www.pcreview.co.uk/threads/error-721-finally-resolved.1574450/ comes in and back out the same router (this I made sure). We use a multi-NAT for routing service request to internal servers. FTP, WWW, RDP, PCAnywhere, SSL, PPTP, MAIL, etc...all these services are routed to internal servers/workstations. We have approximately 32 public IP addresses, hence why we use Multi-NAT for routing public services to internal servers. Everything works perfectly, EXCEPT PPTP (VPN) connections. We have struggled with this for a year now. For whatever reason, it struggles to make a successful connection to our RAS servers. Like I said, it can take up to 6 retries to successfully connect to our RAS servers (up to 30 retries if the remote user is behind a Linksys router). The Fix: Today, I decided to try something different. I decided to use the router's public IP address for PPTP requests, instead of one of the other public IP addresses our ISP assigned us, and simply forward PPTP (TCP 1723 & IP 47) requests to the internal servers. Therefore, the only difference is that I am using a pingable IP address which happens to belong to the router instead of using one of the public IP addresses I have NATed. For whatever reason, this

It error 721 hangs on verifying the username and password. Another machine on the same network, using the credentials of the user who has the problem connects straight away. This has led me to believe that the problem is entirely with the one machine. I've updated the NIC driver with no success. I have created a new VPN connection but get the same results. I have even shut down microsoft vpn error the firewall on the local machine without gaining anything. This connection was working in the past. I have not been able to put a finger on the problem and I am looking at doing a complete re-install of the OS right now. The error returned is "721: The remote computer did not respond."
