Hey,
here are some commands I always seem to have cached in notepad++ they were given to me by my colleague Graeme.
Ping each host in a range:
1: for /l %n in (1,1,254) do @ping -n 1 -w 100 10.146.8.%n | find "Reply"
Fast traceroute using ping:
1: for /l %n in (1,1,32) do @ping -n 1 -i %n 10.146.50.25 | find "Reply"
Find web servers: (a bit slow, needs plink (putty command line))
1: for /l %n in (1,1,254) do plink -telnet 10.146.1.%n -P 80 | find "Server"
Gpupdate all hosts in a range :
1: for /l %n in (1,1,254) do psexec \\10.1.1.%n gpupdate /force
Cheers Bud!
