I'm not quite sure of the terminology so I've used the word "external"
in the subject it may not be correct. :)

Anyway the problem is as follows,

The customer has a DNS server resolving ip addresses for his domain.
mydomain.com but now his users need to resolve addresses which are in a
different domain, remotedomain.com, this domain is not public therfore
forwadig is not possible, and is hosted on remote servers.

How can I set the netware 6.5 server so that when a request for
xxx.remotedomain.com comes it the local dns server forwards the request
to the dns server for the domain remotedomain.com? Is this possible?
