DNS Problems

[ElijahBaley]

Hello

This is the set-up:

NT Server in private IP range 10.10.10.5/24
WINS Server 10.10.10.5
Mailserver 10.10.10.7
DHCP clients 10.10.10.10/24 to 10.10.10.90/24
Router 10.10.10.2/24
DNS Servers are hosted by ISP and have public addresses.

The problem is local name resolution, I have been tweaking WINS and playing around with LMHOSTS files but I now think the problem is DNS related as when I try to ping a local name, some are resolved to the local privately assigned IP address and some are appended with a .co.uk and resolved to a public internet address - the real problem is that my Exchange server (NetBios name 'MAILSERVER') is resolved to
mailserver.co.uk 62.13.129.2 which is not what I want!!

One question, as we use TCP/IP & NetBios locally and use our ISP DNS servers for Internet lookups - is there any need for DNS on my local server.

I inherited this server and it has DNS running with the its local address 10.10.10.5 and the ISP DNS server addresses listed?

Thanks for any help

A DNS server would be an excellent idea. Please see my FAQ on this site for details of how to set it up, and why it makes sense:

How many clients do you have?. As Bcastner said a DNS server would be an excellent idea. However if you only have a small network you may be better off setting up a host file for your network.

Thanks for the tips guys - as it transpired I had a faulty TCP/IP stack and after a reinstall and rebuild of the DHCP and WINS databases everything is ship shape!

We are still running NT so I think that I will stick with WINS for local name resolution until we eventually upgrade to 2000 server and active directory - then I will be checking your FAQ for DNS tips!

Cheers
