DNS

[Ole Ftang]

Hi all,

Got a funny situation going on with DNS on a Windows 2003 domain.

The domain has a DNS structure installed with 4 DNS servers all running an Active Directory Integrated Zone **********.co.uk with no forwarders set so using the root hints for unresolved queries.

When I run nslookup on one of the DNS servers it gives me the DNS server's name of one of the ISP's servers.

Any ideas why the DNS server is using this external server to resolve requests rather than one of the internal DNS servers.

Grateful for any ideas

Long shot, but is the PTR record for that particular DNS server set correctly?

sussed it - muppets have used a live IP range for their internal network and the range belongs to someone else.

PTR records were set by the way.
