Do both DCs have DNS installed?

DNS doesn't usually require much for system resources, if you have defined
your ISP's DNS as a forwarder on the forwarders tab you shouldn't be having
much of a delay, it should certainly be almost as fast as having your ISP's
DNS on your NIC, which by the way, causes errors itself.

When you say:
" > have added 2 DNS lookup addresses from my ISP on the server for
> Forward Lookup. "
Did you add them as forwarders on the forwarder tab or on the NIC?
