Re: DNS resolcing externally for local machines..

Thanx Lanwench..
The clients are picking up the external dns IPs from DHCP scope
options. I have
006 DNS servers (192.168.45.10, 194.72.6.57, 194.73.82.242 ). The DC
has no DNS options set on its NIC, and the only other place the
external DNS servers appear are as forwarders.

Should I remove the external DNS from the DHCP scope options and
simply
leave the internal (192.168.45.10)?

This had worked for a year like this so a tad confused..

Yes, remove the external DNS servers, use only the internal DNS.

I suspect the problem arises from the DNS suffix search list and a Wildcard
record in the public DNS zone for companyname.co.uk. When the client appends
the suffixes it starts at corp.companyname.co.uk
Then companyname.co.uk which hits the wildcard, and resolves to your website
address.

You really need to assign a custom DNS suffix search list containing only
corp.companyname.co.uk. to prevent clients from searching the public zone.

You can do this a a group policy for XP and Win2k3 clients.
