NT4 Server VPN setup

[RISHIDSHAH]

I need to allow a few offsite to be able to connect into our network via the internet. So the easiest way of doing this would be to set up a VPN through the Internet. I have installed the Remote Administration Server on the NT4 Secondary Domain controller and set it to have 3 Point to Point tunnelling protocol connections which will make and receive calls using just TCP/IP.

However everytime I try to establish a VPN connection from within my company with a Win2K machine to RAS server I get an error saying The specified Port is not open (Error 619). What I have done on my client machine to test the VPN out is to simply stop Microsoft network client working so that I simply communicate via TCP/IP and nothing else. With this setting I simply have a TCP/IP address and a subnet ( a bit like a dial up connection). When I connect to the RAS Server, the server initially authenticates me and then gives me this error. So it does go all the way to authenticating me using my Domain user name and password but then gives me this error. The RAS server does initially authenticate me because if I do deliberately put in a wrong password it does ask for the right one and I have set-up the RAS server to allow my user name to connect into the RAS server.

I have set the RAS server to give out any remote client an IP address from addresses currently not being used at my company so there is no conflict. I have also set up the client machine to accept any IP address the server assigns and to use the RAS server's gateway.

I get the same error when trying to connect via a Win98 machine.

As I am doing this within PFE there is no firewall or router between the test client machine and RAS Server.

I have no DHCP or Wins.

thanks

You need to set up an LMHOSTS file on your local machine with the IP Addresses of the resources you need to contact on the network. And you will need to statically assign yourself an unused ip address.
This should allow the VPN to function properly

Thanks for your reply. I made a LMHOSTS FIle and put in my loca W2k Machine in System32\drivers\ect and even imported the file into the TCP/IP settings. However i still get an error after authentication is complete that the specified port is not open (Error 619). I have seen from many threads on this website that ports 1723 and 47 have to be open for RAS to work. How can i find out if these ports are open on the RAS server and on all the clients. However i do point out that i have no Firewall between the RAS server and this cleint machine that i am testing with.

Do these ports automatically open or do i have to specifically opne them on the RAS server and the CLIENT MACHINE?
