I have a Win 2K server with VPN setup. I am able to connect to that server from home and look at files on the HD. Behind the server W2K server (VPN Server) is a Win NT 4.0 machine. This machine is a PDC. The W2K machine is not a PDC or BDC. W2Kmachine is on the same subnet with a static IP address. When I am in my office - I see that the W2K server sees the Win NT server, etc. No problems. When I am at home I have access to the W2K server (VPN server) and I can ping the Win NT server. But I am unable to gain access to the Win NT server. Win NT server does not show up in network neighborhood. When I search for computer, it is still not found. At home I have my VPN client setup on the same IP scheme, in the same subnet as my office. The work Gorup name is the name of my Domain.

Why is it that I gain acces to my VPN server but I am unable to see anything beyond it?

I did make a change to the registry: IPFORWARDING to 1. This seems to not have made any difference.

Any help would be greatly appreciated.

Issue a "net view" command from the remote VPN client.

Do it 2nd time with the domain specified.

Try a "net use" command to a share on the server.

Please report results.

Net View command: alone, w/workgroup name, w/computer name produces the following result: Error 6118: The computer sharing resources in this workgroup cannot be located....

The strangest thing has happened. I tried several times to find my NT server by name and I got no results. All of a sudden it found the NT server (PDC) by computer name. But after finding the computer I issue the Net View and Net USe commands and I get the Error 6118?????

Now mysteriously I am able to get into my server. Nothing is changed on the client side. I don't trust the reliability of this - So if you can pinpoint where I should be looking to resolve what might be a problem I'd appreciate it..

Thanks

if you can ping the pdc from your office the icmp protocol is routable through the vpn.
Ok great. from the command line type nbtstat -A 10.1.1.4 ("PDC IP ADDRESS")

should respond with similar lines

NetBIOS Remote Machine Name Table yourPDC <00> UNIQUE

yourPDC <20> UNIQUE

DOMAIN_NAME <00> GROUP

DOMAIN_NAME <1C> GROUP

DOMAIN_NAME <1E> GROUP

yourPDC <03> UNIQUE

DOMAIN_NAME <1D> UNIQUE

..__MSBROWSE__.<01> GROUP

USERNAME <03> UNIQUE Registered

MAC Address = DE-AD-BE-Ef-00-00

if this does not work the tcp and udp ports are being blocked by the win2k machine

also for future referance. unlike most routers a dual homed 2k machine thinks of itself as 1 metric on all interfaces so you might have to change the forward IP to metric 2 ("instead of one").

let me know if this helps. I got a few more ideas if this doesn't work.

I'm having a similar problem, and to be honest am completely confused. I'm running an accounting app, via tcp/ip. Apparently I have it running fine, however when I connect from more than 1 machine, both machines loose there connection? I'm using a linksys router at home and have am coming in on a sinle dsl ip. even after the sessions time out I'm able to ping both the vpn server (Win2k) and the PDC (Win2k, however am still not able to run the application?
