Exchange not authenticating

I have a WinXP Prof client trying to authenticate to Exchange through a
Cisco VPN 3.0

I can connect and authenticate to all network resources with the exception
of Exchange...it doesn't utilize the integrated single-sign-on that it
normally used to. What I notice in my services applet is that IPSec service
stops upon authentication of the VPN...could that have something to do with
it?

Any ideas or suggestions would be helpful.
 
If you are using the Outlook 2003 client, change authentication security in
Outlook from Kerberos/NTLM to just NTLM.
 
Nope, Outlook 2002...

Have you verified that DNS/WINS name resolution is working OK for the VPN
client? (use NSLOOKUP and NBTSTAT to verify each.)
 
I have had some DNS issues, but only involving a couple of servers that are
co-located through another separate VPN.

What check do you want me to do, specifically with nslookup and nbtstat?

It appears to be working correctly...

nbtstat -r gives me:

Resolved By Broadcast = 0
Resolved By Name Server = 5

Registered by Broadcast = 10
Registered By Name Server = 7

nslookup mymachine gives me:

(on the LAN)
Server: abc-share1.company.net
Address: 10.0.0.65

(on the VPN)
Name: mymachine.company.net
Address: 10.0.2.167

connect to the network via vpn and then do the following.

nbtstat -a <exchange server name>
nbtstat -A <ip address of exchange server>

nslookup -q=A <exchange server name>
nslookup -q=A <fqdn.exchange.server.name>

basically what we are looking for is to see if anything comes back on a
secondary interface that says not found or slow name resolution. By the
way, you didn't mention what version of Exchange is in use, so if it is
Exchange 200x, then do the same tests above with the name of the global
catalog server(s).
 
Ok, here goes:
