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..

Appreciate you help..

An update if it may help any experts, seem odd that I have 4 entries
in the DNS Suffix Search List. On the 2000 member servers & 20003 DC
its only 1 entry which is the corp.OURcompany.

Ding! Here's your problem. You must *not* use any external IP addresses in
your AD clients' DNS settings. Only the internal (usually AD-integrated) DNS
server's LAN IP. Then you use forwarders on the local DNS server itself to
your ISP's DNS server to handle external lookups. AD relies heavily on DNS
and this is a very common misconfiguration - it's easy to fix, however.
Change your DHCP scope so it hands out only 192.168.45.10.
