Looking at DNS on my two domain controllers, if I go into the Forward Lookup Zone, I see I have 54 records, but the 'Name' column has old info that isn't current with the 'Data' (IP) column.
For instance, my laptop's IP address, from DHCP, is nnn.nnn.nnn.41. In the forward lookup zone the name given for that IP address is not my laptop. It's an old computer that doesn't exist any more, as far as I know.
Yes, I am not a DNS expert.
Also, interestingly, I have a DHCP reservation for nnn.nnn.nnn.111 and that matches up in the Forward Lookup Zone with that IP and the correct machine... BUT, if I ping -a the .111 it returns a different computer name.
Do I need to clear some cache or flush something to get that all sorted out in the servers?
I don't want to hose up any user's access or screw up the running systems.
