DNS resolution across Widnows 2000 domains

[wilson2468]

we have the following situation:

Users on the "mycompany.local" Windows 2000 domain,
some servers on the "mycompany.local" Windows 2000 domain, some on the "mycompany.com" Windows 2000 domain. All servers have internal ip addresses in DNS.

The "mycompany.com" servers also have external address that allow connectivity from the Internet.

When I am at the company logged in, I can resolve any server name on either domain by just typing the server name.

If I ping just the server name "Server1" (Server1 being in the "mycompany.local" domain in DNS), it resolves to Server1.mycompany.local and gives me an internal address.

If I ping just the server name "Server2" (Server2 being in the "mycompany.com domain" in DNS), it resolves to Server2.mycompany.com and gives me an internal address.


When I have VPN access from home, I can only resolve the names on the "mycompany.lan" domain.

It does not allow me to resolve names on the "mycompany.com" domain, it is tries to go get the external address.

First:

How can I resolve across the "lan" and "com" domain names by just typing in the server name when I am at the company? I have tried to set this up before and could not, is it the way DNS is configurd?

Second:

When I am connecting via RAS and VPN connection from home, my machine is not a member of the domain, I am just logging in through the VPN connection with my Windows credentials.
Does this have something to do with it?


Thanks

I would suggest you to setup a secondary zone on the other DNS server. In other words:

1. "lan" DNS server should hold the secondary zone of "com" DNS server's Primary zone.

2. "com" DNS server should hold the secondary zone of "lan" DNS server's Primary zone.

Also don't forget to configure zone transfers from Primary zones to Secondary zones.

Hope this will be useful.
