I'm running Win2K3 on a LAN with a DSL connection to the internet. I've got the server set up to be the DHCP and DNS server for the network, forwarding internet requests to our service provider's DNS servers.
This all works lovely, browsing the LAN and the Web, except for a handful of sites which refuse to display (and timeout). If I manually configure an IP address on a workstation, setting the Default GW to the router and the DNS to our service provider's then those sites pop right up. What gives?
I've got a server at our main office that has the same setup and the sites in question are fine. (same DNS servers and all.) I've got different DSL modems at each site, but that's really the only difference. Does anyone have any advice on how to get this to work?
More Details: The server in question is also connected to the server in our main office using MS Routing and Remote services VPN. It also uses AD for DNS storage.
Thanks for any help.
