When auditing the shares and access control permissions on a network – a useful tool is Nirsoft’s NetResView from here
The tool NetResView is a small utility that displays the list of all network resources (computers, disk shares, and printer shares) on your LAN. As opposed to “My Network Places” module of Windows, NetResView display all network resources from all domains/workgroups in one screen, and including admin/hidden shares.
In addition you can then use windows explorer to view the contents of the network share. You can also increase the timeout if required on slower networks or machines. The result can be output to various formats to allow you to compile audit reports for your clients.
