NetResView is small free utility which when executed gets the list of all available network resources that are available through LAN. This includes even the admin and hidden shares from all workgroups and domains.
This is a pretty useful tool that you can use to find all the list of available resources available in the network that you are connected. Another feature that I liked about this software is it displays all the resources that you have shared on your computer. This includes folders, printers, admin shares and hidden shares.
This utility does not require any installation, all you have to do is download and run it and it works out of the box without any issues.
The sad part is that this excellent tool does not work in Windows Vista but works perfectly in Windows XP and 2000.
