MrCompTech...wow! great reply! Sorry I didn't provide more clear info in my post to save you so much trouble.
I am following the standard howto for perfect serve debian lenny with isp3 and mydns.
My main question was ony about getting the local lan to recogize the domains on that server.
my resolv.conf shows only my ISP dns servers. So you're saying I should put the local internal ip of the server as my first dns and the isp dns server as the next 2, correct?
should I only make the change to mydns.conf as you had in the original post.
