Stop / restart the Firewall service. The FW and Web Proxy services maintain their own DNS caches and these maintain entries for ~6 hours. Take a read in the client articles I left on www.isserver.org; it's much too detailed for an email posting.

Problem - With my MS firewall client enabled: When I do an nslookup of the dns name, I get the correct resolution to ip address. But when I do a ping of the dns name, it still tries to ping the OLD ip address. Any ideas why the ping would still try and ping the old ip address with my FWClient enabled? Luq p.s.
