Resolve outside domain name without www

[lacasa]

Our ISP hosts our web -

http://www.sample.com

Our Windows 2003 internal domain name is sample.com

I setup an A record to point

http://www.sample.com

to resolve website internal and this works. The problem is the ISP setup a calendar at

http://sample.com/cal/.

I am unable to resolve this internally.

Next time I will name AD domain sample.local to solve in the future, but how do I resolve now. I believe domain name can be changed with 2003, but my other DC is 2000.

The ISP needs to correct the record. If you add an A record for sample.com pointing to your ISP, you'll foul up users logging into the domain.
