I am running a Windows 2008 R2 domain with Active Directory integrated DNS. All users have laptops and frequently switch from wired to wireless connections (these are on separate VLAN's). It seems the wireless DNS entry is the predominant one which is held in DNS which makes name resolution fail often. For instance I ran wireless most of yesterday. When I came in today I hard wired (and have been all morning). I performed a cold boot of my machine and obtained a wired DHCP address. When I attempt to ping my machine from another device it is returning the wireless IP address from yesterday and thus timing out. What settings should I look for to keep DNS as up to date as possible?
For the zone in question i have refresh interval of 15 minutes, retry 10 minutes, expiration 1 day, TTL 1 hour.
