Domain trust relationship between Active Directory and NT

Hello,

I created a trust relationship between Active Directory and NT domain. It seems to work fine with NT domain administrator from domain server, but when I try to access to a shared folder into a computer from Active Directory domain using other user from NT domain it requests a password.

I checked relationship into Active Directory domains and trust and I this trust relationship is non-transitive.

Should trust relationship be transitive to grant access to all users from NT domain

User from NT domain hasn't password activated. Could it be root cause do not allows it to access Active Directory domain systems

Thanks in advance for your help.

Regards,
