DNS does not update records automatically

[tsap]

When my users connect to are terminal server via VPN. They cannot resolve their own host names with in the terminal server.

But if I go into the DNS and add the "A record" with the current IP and host name, and then do a reload on the forward lookup. It works fine.


Any Idea's?

This is because the IP that the client gets is not really given by DHCP to the client; it's really being given to RRAS services that manages the VPN sessions. The only way I can think of for you to get around this is to create a DNS entry for a particular VPN client and then configure the client to use that specific IP when connecting (and not pull a dynamic address from DHCP). That will bypass the DHCP/RRAS thing which is keeping you from mapping to DNS properly.

currently my cisco pix box is doing the DHCP. I wounder if I change it to my windows 2003 box, if that will fix the problem.

The last servers I had used the windows 2000 DHCP service with WINS, and it worked fine with the cisco gear.

Are your VPN clients configured to register their own IP's with DNS? A Windows DHCP service will facilitate that, while Cisco's DHCP service won't.

When I had my old servers running, this was the config:


I had a range of IP address for my VPN client to use registered in the cisco pix. That range is was not the same as my windows 2000 DHCP range.

on the cisco box I have a VPN range of 192.168.111.70 to 192.168.111.81

on the windows 2000 server, I had a DHCP range of 192.168.111.20 - 192.168.111.51

this setup worked fine on windows 2000 servers.

any idea's?

Go back to the tried and true. Configure a test machine on the w2k3 server and try it. Think you'll like the control you have on the server that you don't have on the pix. Good luck.
