When I do "nslookup or ping mydomain.local" in my local site the domain controller of the remote site responds not the dc of my local/current site. But I know that the local dc is working. The local DCs should respond first before the other DCs at the remote site. How can I fix this issue in Windows Server 2003 environment?

Thanks

This is not the issue,
the remote domain controller is the primary dns server for the dns zone yourdomian.locla
that is why that domain conroller is responding to nslookup and  ping

that is it. and that should be fine unless you want dns resolution to happen in this site
as dc are choosen by  clients and most applications (exchage) in the locat site only (whenever available)





In nslookup you get answer from first DNS from list in TCP/IP properties.
Check this list. Have you answer from first DNS in list?
May be it is server with multi network adapters?

We basically, don't want one site to query from remote site's DCs as long as the local site's DCs are working. Most of our sites are connected through a microwave link(E1) and we want to utilize that link for other purposes such as internet, voice, VTCs, and email. Workstations/servers should only query on its local DCs unless it is down. Is there any workaround to do that?

Thanks.
ok..
then you might want to make one of the domain controllers in this site as seconday dns servers to the dns zone yourdomain.com and set this server on the primary dns servers list on the TCP/IP properties of all servers/clients in this site
(this is for DNS queries )

now. as is said earlier... the queries for active directory are automatically restricted witthin the site
client logons, exchagne server and outlook prefer dcs in the same site so you should be fine
more most of the third party applications follow this practice. so you should be fine

about global catalog queries ...  if you don't want to use wan link ..make one of the DCs in this site as global catalog server.. however this will consume bandwidht for Global Catalog replication
to understand global catalog replication  refer to : http://technet.microsoft.com/en-us/library/cc776756(WS.10).aspx and listed links there

let me know if you i can help you further

Thank you
