How to tell AD to resolve names outside of it's domain ?

[qsdf]

Hi,

I need one-time visitors to be able to resolve "

http://welcome"

when they connect on my LAN. "welcome" is a linux server on my LAN.

My LAN offers a DNS service through my AD server (W2008 - standard). This is defined during the DHCP process initiated by clients.

How do I tell my AD server to accept client requests to resolve "welcome" (not "welcome.corporate.domain" !!) and have them point correctly to the appropriate server ?
I basically need to define "welcome" as a host NOT included in "corporate.domain". => clients must type "

http://welcome"

, not "

http://welcome.corporate.domain"

I've tried modifying my AD's hosts file, it doesn't work. It seems AD doesn't query it's hosts files where queried by DNS clients.

THX!!!
