DNS Zones

[pglover]

In a network using DNS zones - parent and local (please excuse the lack of exact technical terms, but the two chaps that should be covering this are off, and I could really do with some help ;-)

Say ten buildings (A-J), each has local zone and one parent or top level... workstations (ws) get IP from DHCP server in relevant building, WS then seems to lodge name in DNS zone;

only now all WS have registered in only one local zone (Building E) - the WS appear to have correct IP addresses (ie for the building they are actually in) but the DNS entry shows a different IP address - so if I try to ping a ws in building A it reports back an IP that should be in building E and the ping times out. If I check the DHCP and ping the real IP address I get an appropriate resonse.

Many WS are unable to connect/write text file to, to a server in Building E, and I can find no other explanation for that at this stage.

The WS appears to have correct suffix information, and the DHCP service appears to be working OK. It's just the DNS entries that seem to have been thrown into one zone. I don't know how the wrong IP addresses have been allocated to these spurious DNS entries. I am not sure where/what I should be looking for next. Any ideas or suggestions gratefully received.

Many thanks

I dont have nw6 in front of me so I can;t be exactly detailed with my response. Open imanager and view the dhcp config. I beleive this option is in one of the subnets, pick the DNS server you want for dynamic dns updates. Verify that each subnet is updating to the correct dns server.
