Add users from another domain

[Bad boy Warrior]

We have two domains DomainA and DomainB which have a trust between them.

I have a shared drive. If i right click the drive and click share/security i can see the other domain listed under locations and can add the user to the share.

I would like to create a group that holds these users. Once my group is created in AD i click Add and select locations this time i can only see the domain im currently logged onto but not the other domain. Ive typed domainb\user, user@domainb.local etc etc but none of them are accepted. Am i doing something wrong or missed out something? or is it not possible?

Thanks

have you tried logging into domain B, creating the group, and then finding that group while creating the share on domain A?

have you tried logging into domain B, creating the group, and then finding that group while creating the share on domain A?

Would that be the preferred way or is that by default?

I'm not sure it was just an idea I really don't know about trusts, I've never put one in place

If these are two distinct, separate domains in different forests (and not just two child domains in a single forest), then yes, this is the preferred way to accomplish this. You can review this technet article for cross-forest access to resources if you want to try a different method, for instance creating a (security, not distribution) global group in domain B, adding the domain B users to the global group in domain B, and then creating a (security) universal group in domain A and adding the global group from domain B to this new universal group. Note that this will only work if you are in 2003 native or higher on both domains.
