VPN File Connection Issue and Windows 2000 Client File Connection issue to Windows Server 2003

Posted on 2006-11-25
Last Modified: 2010-03-18
I'm not sure if these two problems are related but they both happened on the same day so I'm thinking they are.  I'm running windows 2003 server.  A few things I'm running.... DHCP, DNS, RRAS. Not running WINS.

The first problem is with my VPN. It's a pptp connection.  The clients are able to connect to the VPN.  They just can't connect to files.  Old short cuts stopped working.  I tried putting the server host name in the address bar as well.  I can ping the server using the DNS name and the ip address.  I can't browse the network either.   I am able to RDP over VPN.  

The other problem is with a windows 2000 client on the LAN.  They are able to connect to the internet. I can ping the server with the IP address.  I haven't tried pinging with the server hostname yet, but I'm guessing that will work  I wasn't able to connect to the server by entering the host name into the address bar either.  It seems as if all the network clients this having this particular issue although they aren't having a problem connecting to files through mapped drives.  I wasn't able to browse the network from the windows 2000 client either.

Any help would be appreciated.  Thanks in Advance!

Well, since when using a VPN to connect clients to the local LAN, you must use separate subnets, you might want to ck that first...  and since browsing does not work between subnets unless you are running WINs in each subnet, it is not surprising that you cannot browse the network from the remote clients...  can you connect to a share using the Run Line?  

\\computername (or IPAddress)\sharename (or C$)

The IPs the VPN clients get are from the same scope the same as the computers on the LAN so I believe they are all on the same subnet.  Do I still need to run WINS?  Will this still help the issue?

I can't connect to a share using the run line.  Host name or IP.  This is the same for the VPN computer and the win 2000 client.  It worked a few months ago by ip address, but not by server host name.

Thanks for replying-

Then that may be your problem..  Your clients must be on a separate subnet when connecting via a VPN...  

RobWill outlined the proper setup for a Server hosting VPNs in another thread..  here is his comments on the setup:

The basic server and client configurations can be found at the following sites with good detail:
Server 2003 configuration:

Windows XP client configuration:

You will also have to configure the router to forward the VPN traffic to the server. This is done by enabling on your router VPN or PPTP pass-through, and also forwarding port 1723 traffic to the server's IP. For details as to how to configure the port forwarding, click on the link for your router (assuming it is present) on the following page:

The only other thing to remember is the subnet you use at the remote office needs to be different than the server end. For example if you are using 192.168.1.x at the office , the remote should be something like 192.168.2.x

Once this is configured you can then use services similar to how you would on the local network. You will not be able to browse the network unless you have a WINS server installed. Also depending on your network configuration you may have problems connecting to devices by name. Using the IP address is less problematic such as \\\SharenName. If you want to resolve NetBIOS names we can elaborate on how to "fix" that, if not working properly.

Thanks I will look over these.  I was able to get the 2000 machine up and running by reinstalling TCP/IP and re-adding to the domain.  The client wants to wait on the VPN connection for now.  I will wait a few days and then close this out.  Appreciate your help so far.
