How do I Access Network Shares and Exchange when connected to a Linksys VPN router?

I have a server that sits behind a Linksys VPN router.  The server is running Windows 2000 sp4 and Exchange 2003.  I can successfully connect to the VPN router and ping all computers and printers on the remote network, I have even been able to print to one of the remote printers.  I can not however access any Shares or have Outlook successfully connect to the Exchange Server. In essence, the Domain doesn't seem to recognize me.  Finally, do I have to have the client computer be registered to the same domain that is on the remote network?  This is not the case right now.  The client is running XP Pro.  This seems like a usual situation but I have yet to find an answer.

Thanks for your help

sounds like name resolution over VPN, quoted http://howtonetworking.com

Unable to browse through PPTP/VPN connection
Symptoms: 1. If the WINS server is on the same computer as the PPTP/VPN server, and you attempt to connect to a computer using a PPTP/VPN client, you may experience following problem: 1) The NetBIOS name of the computer to which you are attempting to connect is not resolved. 2) You may receive an error message similar to the following error message: "System error 53 has occurred.  The network path was not found" when using net view or opening Network Knighthood.
2. If the WINS server is not on the same computer as the PPTP server and you attempt to connect to a computer using a PPTP client, you may be able to connect to computers on your local area network (LAN), but you may be unable to connect to network shares or resources on the PPTP server.
Resolutions: Inability to browse often means the client can't resolve NetBIOS names.
1. If this is a workgroup network, enable NetBIOS over TCP/IP on the server and clients.
2. If this is domain network and the WINS server is on the same computer as the PPTP/VPN server, move the WINS server to a different computer.
3. Add the NetBEUI protocol for your PPTP tunnel instead of, or in addition to, TCP/IP.
4. By default, most routers and firewalls prevent the transmission of NetBIOS names unless you enable UDP ports 137 and 138 and TCP port 139. Try to enable UDP ports 137 and 138 and TCP port 139 across all routers and firewalls between the PPTP/VPN client and PPTP/VPN server.
5. Make sure the client has correct DNS, WINS and Master Browser settings.
6. Make sure the default gateway points to the remote network rather than to the ISP.  
7. Some ISP might block ports required for NetBIOS name broadcasts.
8. If WINS address is not distributed upon connection to VPN, LMHOSTS should be configured to enable Domain to be located.
9. If you try these techniques and the client still can't browse, try to use UNC to connect to the remote resources by ip, for example, use the net use h: \\serverip\sharename command.

another shortcut is to add that server (those servers?) to hosts and lmhosts in windows\system32\drivers\etc

shares tend to rely on lmhosts, outlook on hosts

for example, in lmhosts

192.168.1.2     servername     #PRE #DOM:NETBIOSDOMAINNAME

and in hosts

192.168.1.2     servername

type nbtstat -R at a cmd line to refresh the lmhosts, or just reboot.

after that, typing \\servername in the run dialog should work

I did your suggestion and I still am getting the "path not found" when I try to map a drive.

can you ping the server by name?  just 'ping servername'

If I use the IP address in place of the server name it still gives me a "path not found"

I can ping the server by name by opening up the ports on both routers and modifying the lmhosts.  But I still get the "network path can not be found"

Any ideas
