AccessChk is a free Sysinternals command-line utility that shows what access a user or group of users has to a particular service, file, folder or registry key. It returns deeper results than what's available through access control lists, showing rights associated with every file and directory within a given system in order to identify permissions errors.
To use AccessChk, an administrator inputs a user or group name and an object to audit, using commands documented within the program. It is only possible to audit a single user or group at a time.
AccessChk offers similar functionality to AccessEnum, but without the graphical display.
