Why is Exchange or server access disallowed?

It appears that something is blocking traffic to my SBS 2003 VPN connection.  The SBS authenticates the user and resides on the tray but does not let the user connect to the exchange server.  On another laptop (different location) it works just fine.  The laptop is running McAfee ASAP firewall.  Does PPTP have to be allowed on the router?

I can hover the mouse over the SBS VPN in the system tray and see the packets sent and received but when I try to access the server through the run command \\servername it does not resolve (only on this problem laptop)  the other laptops work perfectly.

Hi cwpcguy,

Can you access the server by IP address?

\\ip.add.re.ss

Have not tried... BUT IF the answer is yes then should I edit the lmhosts file?  Even opening Outlook (with Exchange connection) returns server not found.

No, that wasn't going to be my proposed solution if it worked.

If it works by IP, then try by pinging by FQDN,

ping server.domain.local

If THAT works, then what I would suggest adding the dns suffix to the VPN connection (tcp/ip / advanced / dns)

Post an IPconfig/all from server and laptop.

If this is only happening on one laptop, is it only happening when that laptop is being tested at ONE location?  Because your question of if PPTP has to be allowed on the router is close... GRE Protocol 47 has to be enabled and open on the remote router (as well as on the SBS's).  This is generally called VPN Passthrough, or PPTP Passthrough if not explicitely called GRE Protocol 47.  

There are various tools that can be used to test what's happening:  http://www.microsoft.com/technet/community/columns/cableguy/cg0105.mspx

But I'd say that your best guess would be to check for GRE.
