I need some help with the reverse lookup zone table on my Windows 2000 server. I have multiple names for most of the IP addreses and this is obviously wrong. I beleive a new entry is created if the client has obtained an alternative IP DHCP address, or maybe when the client PC has been rejoined to the domain (But they are only guesses) The entries are similar to the following:-
192.168.10.100 Pointer zurich.mydomain.local.
192.168.10.100 Pointer bilge.
192.168.10.101 Pointer thecon.mydomain.local.
192.168.10.101 Pointer sphere.
192.168.10.103 Pointer centurian.mydomain.local.
192.168.10.103 Pointer kingston.
192.168.10.104 Pointer amidala.mydomain.local.
192.168.10.104 Pointer amidala.
192.168.10.105 Pointer kingston.mydomain.local.
192.168.10.105 Pointer overtone.
192.168.10.106 Pointer bismarck.mydomain.local.
192.168.10.106 Pointer calcium.
192.168.10.107 Pointer fred.mydomain.local.
192.168.10.107 Pointer maul.
192.168.10.107 Pointer norton.
I have no real problems on the network at the moment, but I have had some issues with group policy failing at login from time to time on several pc's.
Does anyone know the answers to the following:
1. What could cause the multiple entries to be created
2. When does the reverse table get used?
3. Can I recreate the table on the fly to correct the problems
4. What effect could I see if I didn;t rectify the problems
5. Why do some of the entries in the table have the extension .mydomain.com as opposed to just the name?
