accessing resources through a

hi all,

i have a question about accessing resources in another domain through a 2 way non transitive trust. we log on to domain A and access a resource in domain B. when I look at ntfs permissions on relevant files and folders in domain B I can not work out how access is provided currently. there are no explicitly listed permissions listing accounts in domain A for me to edit- any ideas of where to keep looking- i’m assuming this is something to do with the trust? Currently the resources in domain B are too accessible- I’ve been asked to reduce perms to read and print. thanks
