I have a file share in a resource forest, which users in another forest need to access.
There is a two-way trust between the two forests.
If I create the share with Read permission to Everyone, on a memberserver in the resource forest, then it's not possible to access the share at all.
If I create the share with Read permission to Everyone, on a DC in the resource forest, then I can access the share from, but inly from a DC in the user forest, and only with admin credentials from the resource forest.
What must I do to allow a plain users to access a share on another forest, without any logon prompt?
