Seeing who's logged on your network....

Here is the batch file that answers the question of how to find out who is logged on and sharing what shares and loggin it to a file. The only extra file you need is alive.exe which is a freeware ping replacement. The syntax is ipscan.bat 111.111.111 leaving the last octet off to auto increment.

@echo off
rem begin ipscan.bat
