Single Domain! Multiple Zones

[karthikeyan Krishnan]

Hi all,
Iam involved in a migration of a Windows NT4.0 Domain to
Windows Server 2003 Active Directory Domain.

Its a multi location domanin currently having one DNS zone
per location.
Ex: host.site.domainname.com

Since its a inplace upgrade and a single domain Active
Directory model, the DNS has to be restructured to
Domainname.com and their after hosts will be registered
as "host.domain.com" which is not supported by some of the
home grown applications.

So is there a way to configure DNS to use
host.site.Domainname.com?

Warm Regards,
Karthikeyan.K

I'm not sure if I'm understanding the problem correctly, but you might
be able to use CNAMEs for this.

In other words,

host.domainname.com IN CNAME host.site.domainname.com

or

host.site.domainname.com IN CNAME host.domainname.com

Sure. Just add a zone for site.domain.com, standard primary is fine.
Add the host record and you'll keep the legacy apps happy.

You are right steve. but the CNAME will help in case of
fwd lokups.. but my requirment is that applications that
are going to respond for the user query will do a reverse
lookup to check the user has a valid FQDN registered with
the DNS server in this situation the application will
check the format host.site.corp.domain.com
