FQDN and new alias name

Hi folks

I have a local Windows domain called

oxford.stclares.ac.uk  using MS integrated AD and DNS

machines FQDN's are automatically registerred in our dns as machine_name.oxford.stclares.ac.uk

we have an external DNS record setup with our ISP email.stclares.ac.uk which is forwarded to our external IP which is natted to our webmail server.

People on our Lan who wish to access this service allways resolves to our outside IP which will fail from local access so they need to type in email.oxford.stclares.ac.uk to get to the webmail services.

I need to register something in our DNS that our local DNS will resolve email.stclares.ac.uk to our local IP address.

Under forward lookup Zones We have oxford.stclares.ac.uk, Anything I register (new Host (A) or Alias (CName)) will have this as part of the fqdn i.e. email.stclares.ac.uk.oxford.stclares.ac.uk
Obviously not much use

There must be a way round this as I think think this is a common scenario. Do I need to create a New Zone or am I missing a trick here.

TIA
Jo

Here is my formula to make things work...
------------
Go into DNS manager..

First create your reverse zone if not done already

Right click on REVERSE ZONE, and then create the zone using 192.168.1.
next right click on FORWARD ZONE
then choose primary and enter in mysite.com
once the forward zone is created, select THAT zone (mysite.com) and right click
add an A record choose the default settings and make sure there is a checkmark on create associated PTR record
right again on THAT zone (mysite.com), choose CNAME (canonical name), enter 'www' as the alias, and the IP address 192.168.1.x.  (make sure you have that last "." after the 1.) where x is your server.
right click on the server and choose update server datafiles.

Create an AD integrated primary zone "stclares.ac.uk" in your internal DNS server and add an A record (email) with the internal IP address of the owa server.

Be careful and test it, you can break things because internal users can no loger resolved external addresses in 'stclares.ac.uk' domain.
