Creating a Two AD Domain Trust

Hi Experts,

I am in the process of creating a project plan to create a two AD Trust between two domains.

One domain is running AD 2003 Functional/Forest levels and the other is running Windows 2008 R2 Functional/Forest levels.

Can you recommended the best practice/procedure to accomplish this project?

Should I use a stub DNS Zone vs a Conditional Forwarder etc.

It is depend on need, if you need this trust to be keep for a long running cause, I will recommend using stub zone since that keep updated with any NS changes cross forest.

if this is short term trust such as part of migration best suit is Conditional forwarder

I was able to successfully created the two way trust between the domains.  I have a security group in domain A that I need to add some users from domain B.

The security group that is in domain A is a Global group. When I tried to add users from domain B to domain A, I do not see the option to change to domain B location.

Any thoughts  on what I am missing ?   Thanks

Hope you need to add users from Domain A to provide permission on Domain B. I recommend change the Group scope to Domain Local.

I do not follow ??

You have mentioned "The security group that is in domain A is a Global group", you may change group type to Universal then to Domain Local group, since you may not able to convert this directly in to Domain Local group
