need default domain badly

[BRElliott at gmail.com]

I work for a company that was forced to move our datacenter in lieue of
hurricane  Rita.  I know it's not proper but let me get to the point of
what I need.  I need to temporarly have host queries resolve to a
domain if it's not specified because (somehow) this used to work
before.

Example.
Client queries for host1
 - I need this to hit the dns server and search through my host files.
So this would resolve to host1.mydomain.com automatically if the domain
is not specified.  

I'm using bind 9.1.3

Thank you so much!
