DNS A Records not updating
Posted on 2008-09-29
I have a DNS server running AD Integrated in a Win2k3 Native Environment
My DHCP Server is set to update DNS and PTR records always.
I have 50 machines on one VLAN that just changed VLAN's a couple days ago.
Now all 50 machines are not pingable by host name. Instead it returns the old IP Address. Registering the machines does no good obviously because the host records still exist and you can't have two machines with the same name in DNS even though the IP has changed.
It's not profesional to wait 7 days for the records to scavenge obviously when all 50 machines are not pingable by host. They actually have to get to their file servers which is on their VLAN as well but I'm not sure if this can cause other issues like Group Policy and stuff that requires the DC to push down infnormation.
Can anyone explain this phenomina and show me how to correct it so next time I don't have to manually delete all 50 freakin records? I mean I'm lucky it was only 50. If I knew how the problem was created I can prevent it from happening next time we do VLAN changes or fix oter isolated incidents which seemto creep up now and then...
Thanks a ton everyone
