answered myself, but i wonder if this is resolve the accessing the intranet site problems I was having
Symptoms: after establishing VPN, you can't ping the server name. However, you can ping FQDN, for example, server1.chicagotech.net.
Cause: Missing the DNS suffixes. For the consultants,, refer to 072604RL
Can't ping VPN client by name
Symptom: you can ping the vpn client by ip but when attempting to ping a vpn client from remote LAN, you get time out.
Resolution: 1) if you have correct DNS and WINS settings, you should be able to ping vpn client by name.
2) If you get the time out with a different ip (for example, ping ip is 192.168.100.7 and real ip is 192.168.100.13), check the dns and wins records and delete the 192.168.100.7.
3) If the dns and wins records don't show the client record, make sure it points to the same and correct dns and wins.
4) If the VPN client doesn't register its DNS, you may need to go the VPN connection properties>networking>TCP/IP. On the DNS tab, enter the DNS server IP in DNS suffix for this connection and check Register this connection's addresses in DNS. Or use ipconfig /registerdns command.
5) Also make sure all computers are pointing to the same DNS.

If you can only browse computers by IP and not hostname then you need allow UDP port 53 (DNS) to forward requests to the domain controller internally for the ability to resolve names across a VPN.
