Will a secondary zone for a domain trust allow me to query by NetBIOS name or just FQDN

I am going to be setting up a forest level trust, I already created the conditional forwarder for the other domain and can ping by FQDN.

I would like to be able to ping by NetBIOS name so I don't always have to type in the FQDN. Would creating a secondary zone allow me to do this or will I still have to use the FQDN.

Is there anything I can do to ping by NetBIOS name to save me typing?

You can append DNS suffix list on client in order to provide them a complete list of domains.
Each domain name will be processed in the order until the host is found.
Since Server 2008, there is the concept of global zone to realize this:
- http://www.petri.co.il/windows-DNS-globalnames-zone.htm
- http://download.microsoft.com/download/e/2/0/e2090852-3b7f-40a3-9883-07a427af1560/dns-globalnames-zone-deployment.doc
I'm not sure if secondary zone will provide what you want to achieve.

If you want to be able to ping by netbios name you are going to have to add the dns suffix for the secondary zone into your dns suffix search order.  If you are doing this on a per machine basis it's in IP settings for the NIC under DNS.  This can be done via GPo also.

Nice, the DNS suffix was what I needed along with the conditional forwarder.

With regard to GNZ I browsed over the links you sent me. Would it be a true statement that GNZ is better for a larger organization that might have lots of DNS suffixes or an IPv6 environment?

We only have 1 conditional forwarder at the moment and I could only see us adding 1 maybe 2 more in the future.

From reading the offical MS document on GNZ I woudln't rely on it as it probably won't be around for long.  Go pure DNS and you will be better in the long run.

OK, I am going to stick with the conditional forwarders and DNS suffix. I setup a one way external trust and I was able to confirm it works by giving RDP permissions to another user account in the other domain.

What I just tried to do that didn't work was to add user1 from domain2 to domain1into the AD domain admin groups. I only have the option to search in the local domain, do I need to change it to a forest trust instead of external?

you say you added a one-way trust.
so you can add accounts from one domain to the other, but not do the reverse operation.

To do this you need a two-way external trust, or bidirectionnal forest trust.

I ended up setting up a two way forest level trust after raising the forest functional level on domain2 to 2003 server and then I was able to add users from the other domain like I was looking to do, thank you.
