How to setup domain trust between Windows 2008 and 2003 server??

Can anyone give me step by step instructions how to do this, starting with setting up the DNS all the way through the trust on the Windows 2008 domain?

Here is my senario,

I have a Windows 2008 Server, domain controller running in 2008 functional level.

Server Name
Server1.domain1.local

I have a Windows 2003 Server, domain controller which is an external domain

Server Name
Server2.domain2.local

I would like to create a trust when people login to their PC's they can select either domain in the drop down to login too.

Thank you for the steps for creating this.
Hello,

this description is not complete.
Please can you tell me detailed what I have to do on the DNS on both sides and how to setup the trust ?
I cannot setup the trust now because no FOREST TRUST is available.

I think I have to do some DNS settings, but the description for the DNS is not complete, sometimes they write zone and sometimes SECONDARY ZONE. Please can you be more detailed ?

what exactly is to do in the dns ? this info I got.

Okay. I made the assumption that the DNS servers are the Domain Controllers. I also assumed good connectivity between the DNS severs. We will call SERVERA the Domain Controller from ABC.com and Server1 from the 123.com domain. Here are the DNS steps that you could use:

   1. On Server1 log on and access DNS.
   2. Right Click on the zone 123.com and click properties.
   3. Got to the transfers section and configure the server to allow zone transfers to the SERVERA IP address.
   4. On SERVERA log on and access DNS.
   5. Right click on the zone ABC.com and click properties.
   6. Go to the transfers section and configure the server to allow zone transfer to the Server1 IP Address.
   7. Still on SERVERA, create a SECONDARY zone called 123.com.
   8. Indicate that the Master server for the 123.com zone it Server1.
   9. On Server1, create a zone called ABC.com.
  10. Indicate that the Master server for the ABC.com zone is SERVERA.
  11. Check that the Zones are correctly populated by accepting your changes and then double-clicking on the new zone.

You are now ready to set up the trust.
