My ISP (zoomtown) has begun a new tactic that is interfering with my companies VPN access. Basically from what I can tell, my ISP has started redirecting unresolvable address to a stupid default 404 page that says something to the effect of, oops, you type the address wrong, here are some adds. We are using routing and remote access inside a windows 2003 environment. Our employees when using the VPN are no longer able to resolve internal address because they keep getting redirected to zoomtown's default page. I need to figure out how to move our VPN's dns priority above the ISP's. Any thoughts, suggestions. or comments?

ps. Adding entries into the host file does work, but I would like to resolve this from a dns stand point.

when you're connected by VPN the first thing your 'server' does is try to resolve the address localy (including LAN/VPN ranges). if there's nothing to be found it continues to other dns

so in short, you're not being compromised by your isp
