Weirdest behaviour - dns or active directory?

Hi People


I have 2 dcs both run dns and one runs dhcp (dhcp server 10.0.0.2)

when i run the following command on my DC DHCP server one

netsh dhcp show server

it reports 2 dhcp servers called server01.mydomain.local (my only DHCP server with ip 10.0.0.2 and another with another private ip 192.168.1.2)

i changed the ip of the dhcp server from 192.168.1.2 to the 10.x.x.x range like a month ago but it appears that there is still a reference to it

I guess this is more of an active directory thing as it says the records were found in the directory service the really weird thing is that if you ping that now non exitant 192.x.x.x ip address you DO get one response but it is from my WAN ip reporting net unreachable- now what on earth is going on there? the other 3 packets sent by ping fail to come back

I have pasted the result of the above netsh command and the result of a ping - can anyone please explain what is going on here and also how can i remove the old 192.x.x.x dhcp server from the directory THIS IS WHAT I REALL NEED TO KNOW

C:\Documents and Settings\manager>netsh dhcp show server

2 Servers were found in the directory service:

Server [server01.mydomain.local] Address [10.0.0.2] Ds location: cn=10.0.0.2

Server [server01.mydomain.local] Address [192.168.1.2] Ds location: cn=192.168.1.2

Command completed successfully.

C:\Documents and Settings\manager>ping 192.168.1.2

Pinging 192.168.1.2 with 32 bytes of data:

Request timed out.
Reply from 83.146.17.222: Destination net unreachable.
Request timed out.
Request timed out.

Ping statistics for 192.168.1.2:
Packets: Sent = 4, Received = 1, Lost = 3 (75% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms


Does anyone know if this record in AD will cause a problem? have checked dns and there is nothing i can see relating to this old server so how does AD resolve 192.168.1.2 to server01.mydomain.local - is this ALL cached somewhere from as long ago as a month - it could well be more

there is probably a simple explanation but where is it?

thanks in advance

Simon
