Here is the issue we are having:
Our remote users use Vista Enterprise SP1 on Laptops and connect to our network via a Cisco VPN client connecting to a Pix 515. We have never had an issue before, but now with Vista, it seems to override the DNS entries, putting their ISP DNS first. This is usually not an issue either, except for some ISPs are now redirecting erroneous pages to a search engine instead of checking the next DNS entry. Our VPN client does use DHCP to put in the correct corporate DNS, but when one of our servers are entered, the ISP DNS cannot find it and therefore redirects them to a search engine.
My question: Is there a way to override this or have the client supercede the host DNS entries in order to put ours in the top of the order?
IPV6 is disabled in the clients already and we have considered using a hosts file, but would prefer a DNS fix instead of hosts entries. This is critical that we resolve this as our remote sales people run across this problem in various hotel settings mainly.
I hope I have explained this correctly.
