VPN and Exchange Issues

I am running a VPN server via my ISA 2000 W2K SP-4 remote access server. My
client gets an IP, WINS, DNS info from DHCP server - which the ISA 2000
server is acting as, as well. When I make my connection successfully, I try
to connect to my Exchange server via Outlook 2003 but it cannot find the
server. I then try to ping the server_name and no matter what server_name I
try to ping (we have 7 servers), the ping fails. I noticed the information
recv'd from the ping attempt and it says servername.COMPANY.NET
[64.15.175.5]

My client PC is officially part of the domain, but is off site when testing
this, using a broadband connection for my VPN. I log into Windows XP Pro
SP-2 like I would if I was at work (ie: using the domain name, not the local
PC name), then I make my VPN connection. My local PC IP address is
192.168.7.x (obtained from a broadband router acting as a DHCP server) and
my connected IP address from the office DHCP server is 192.168.1.x

Again, no matter what host name I try to ping, server or client, get the
same wrong address. Then I try to open up a network share, using netbios
name and it connects fine. (ie: \\servername\sharename)

I also did an IPCONFIG /ALL and noticed my info for the VPN connection as:
ip address - 192.168.1.35; subnet mask - 255.255.255.255; DHCP - NO;
gateway - 192.168.1.35; DNS - 192.168.1.1 and 192.168.1.2; WINS -
192.168.1.2 and 192.168.1.5

Not sure why I get the 64.15.175.5 address when trying to ping, but that is
why I cannot see my Exchange server - it is not the correct address. If I
use the server IP address, I can ping it fine. I do not see the 64.15.175.5
address in any of my DHCP registered addresses, nor in my WINS/DNS
registered addresses.

Any ideas?

TIA,

-Tom
 
Check and make sure you do not have an outdated entry in the lmhosts file,
you might even want to add your exchange server to it and see if that helps.

Could you show the entire IPCONFIG /All just as it outputs it?

There are no LMHOSTS or HOSTS files on this system.
