registering with dns
Posted on 2009-07-10
when a client connects via vpn with their laptop from home, they get a 10.10.50.x address from the cisco asa dhcp server. everything works fine. ok. they come into the office and plug into the network, and get a new address - 10.10.10.x or 10.10.20.x..
ok, the problem is that the dns server still has the 10.10.50.x address. i have set the scavenging/aging down to 12 hours for the refresh interval, and 12 days for the non-refresh... the defaul is 7 days for each.
in order to resolve this, i have to delete the A record and do an ipconfig /registerdns in order for the dns server to update the database with the new ip address.
any idea how i can fix this problem?
