Security groups from trusted domain   

I added a Universal security group from a trusted win2k3 domainB as member of 
a local domain security group of domainA but I cannot access resources in the 
relative shared folders of domainA.
I can only if I add separately the security group of domainB , but in that 
way I have to visit all the folders.
Any workaround ?

TIA
