Name Resolution on VPN
Can ping FQDN but not host name Can ping FQDN but not host name 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. Add the DNS suffixes to the VPN client or setup WINS. For the consultants,, refer to 072604RL 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. Connection issues on DC, ISA, DNS and WINS server as VPN server Symptom: You have a Windows 2000/2003 server is configured as VPN running DNS, WINS, you may experience some connection issues. 1) the internal computers can't ping the server by name; 2) if the server is a DC and Master Browser, you may have a computer browsing issue; 3) you may receive Event ID: 4319 - A duplicate name has been detected on the tcp network; 4) You may receive error messages like "No Logon Servers Available to Service your Logon Request" when you try to open file shares or map network drives to the Routing and Remote Access server; 5) if the server is also a DC, you may not be able to logon the domain; 6) if the server is also running ISA, you cannot browse the Web from client computers on the local network, regardless of whether the computers are configured to use Web Proxy or the Microsoft Firewall Client. For example, "The page cannot be displayed" may appear in the Web browser with a "cannot find server or DNS" error message.
Cause: When a VPN client connects to the VPN
server, the server creates a PPP adapter to communicate with the remote
computer. The server may then register the IP address of this PPP adapter
in the DNS or the WINS database. When the internal computers try to
connect to the IP address of the PPP adapter, them cannot reach the PPP
adapter, then the connections fail.
How to assign DNS and WINS on VPN client manually Name resolution is big issue in VPN access. If your VPN server doesn't setup correctly or the VPN client can't receive the VPN DNS and WINS settings, you may setup them yourself. To do this, go to the VPN connection>properties>TCP/IP properties>Advanced. Click DNS and WINS tabs to assign the VPN server's DNS and WINS. Name resolution Issue in a VPN client To assign the DNS and WINS to a VPN client for name resolution, you should configure VPN server with the IP addresses of the appropriate DNS and WINS servers. The VPN client inherits the DNS and WINS configured on the VPN server. If name resolution does not work from the VPN server, it will not work for VPN clients.

occur: 1. Internal clients may no longer be able to browse the Web.
