Question : Domain trust between Windows Server 2008 R2 and Windows Server 2003

Disclaimer: I know enough to be dangerous, and the "dangerous" has proven itself a few times over the years, but I love experimenting.  This is also my own business, so I can assume full responsibility for any actions taken.

I found a thread on here that spoke to a similar situation, but I have been unsuccessful in my attempts to create a trust between my two servers.

- Server1.Local is a Windows Server 2003 domain controller and Server2.Local is a Windows Server 2008 R2 domain controller and both are in two different locations for two separate businesses.
- I need to have access to both domains from my laptop.
- Server1.Local is in a location with a Static (internet) IP address and a Sonicwall firewall with a VPN connection configured.  The VPN connection is used on my laptop but I would like to use it on Server2.Local.
- Server2.Local is in a location that does not have a static (internet) IP address
- I just set up Server2.Local to be a domain controller yesterday using the DCPROMO.exe wizard.
- I have successfuly connected my laptop to the (new) Server2.Local domain controller at the expense of losing a domain connection to Server1... No problem, I'll set up Domain Trust between the two domains, right?
- I have gone into both of the Active Directory Domains and Trusts and done the following:
          1) Right clicked on the Domain and clicked Properties
           2) Clicked the Trusts tab and gone through the "New Trusts" wizard
           3) I was only able to create a "Realm" trust on both of them

At this point, that's all I've been able to do.  The trust "shows up"  in the trusts tab for each of the servers, but I have yet to be able to log on to both servers without destroying the other domain connection.  I know I'm missing something but I don't know what that might be.  

This has been summarized, so please let me know what other information you might need to answer this question.  Thank you!!

Answer : Domain trust between Windows Server 2008 R2 and Windows Server 2003

I will look into your question but first I want to suggest a Sonicwall @ location2 and connect the 2 locations VIA VPN.
I know you said the second location isnt static but you only need 1 location to be static with Sonicwall's.

You can create a site to site VPN (also called a point to point) and put the Sonicwall's into agressive mode instead of main mode.

I can walk you through it step by step if needed, I have installed about 20 or so Sonicwall's in this configuration and currently work for the nations largest firewall management and monitoring service company.

Then you can get the 2 DC's to "talk" to each other.
