This connection was working in the past. This is a log file created by the above command to keep track of what was done. How to fix the Error 721 To resolve this error, you need to configure the network firewall so as to permit the GRE protocol 47. You need to check for three possible causes of this problem. his comment is here

Sometimes firewall software packages (including some versions of Check Point Software Technologies' FireWall-1) don't accept PPTP connections when you configure the firewall with Network Address Translation (NAT—for information about NAT, see For details about that see the following link.

If your RAS server can browse the network, clients should also be able to browse the network with the same settings. It kills me that I can make WINS and DNS work, put in all kinds of static routes, and still not be able to browse the network, despite being able to

You will not be able to browse the network unless you have a WINS server installed.

  3. One way to figure out why your SQL queries take so long is to time responses on the LAN and relate them to your LAN connection speed (10Mbps or 100Mbps), then

  10. Many readers experience these problems, especially the domain membership configuration problem.

An inability to browse usually means the client can't resolve NetBIOS names. Then the client can browse all LAN resources. To enable PPTP filtering, right-click Network Neighborhood, select Properties and Protocols, double-click TCP/IP Protocols, and select the WAN adapter and Advanced. Hello and welcome to PC Review.

So you can make stable VPN connections. To establish a PPTP tunnel, the client and server exchange GRE packets, and some ISPs disable external GRE packets because the ISPs use GRE internally to manage routers.

The Problem: It can take up 6 retries for any remote user to successfully created a remote PPTP connection to our servers. Then look under dependencies and see if there is a common service. I have four more recommendations to help you keep the server configuration simple and straightforward for troubleshooting purposes. On one of my networks, I can browse clients and map to clients at will.

So it seems to be getting to the host. Everything works perfectly, EXCEPT PPTP (VPN) connections. The error I got is TCP/IP reported error 733: Your computer and the remote computer could not agree on PPP control protocols. 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
