What is "Assoc-NT-Account"? "ADSI has a Lightweight Directory Access Protocol (LDAP) provider that can be used to retrieve information from the Exchange directory. The mailbox attribute which stores the Primary Windows NT account has an LDAP name of Assoc-NT-Account. The Assoc-NT-Account attribute does not contain the security account's textual name, but rather a binary string representation of the SID." See ME251390 - "HOW TO: Find Exchange Recipients Associated With an NT Account"
