Win98 VPN woes

We get Error 751: “The remote computer refused the VPN connection.” If we change the DNS to a different name, we get a different error message. What can we do?

We are trying to build a VPN. At our first location we have a Windows 98 machine connected to the ‘Net. We set this machine as a dial-up server and added user TSTWAN with no password. The machine has a static DNS name, www.tstmyconnection.com, which we created using trial software. The second location has users trying to connect to the first location using a VPN connection with the user name TSTWAN.

We get Error 751: “The remote computer refused the VPN connection.” If we change the DNS to a different name (such as www.tstmybogusname.com), we get a different error message. What can we do?

The 751 error might be the result of an intermediate device refusing to handle the packets.

Verify that the machines at the second location map your static www.tstmyconnection.com host name to the correct IP address using ping or nslookup.

If not, try the server IP address in the dial-up connection server identification dialog. Also, put a password on your TSTWAN account to make the test more realistic and verify that the client settings exactly match the server settings for the VPN.

Also, the Point-to-Point Tunneling Protocol ports need to be open on a firewall for traffic to flow.
