Here are my notes from listening/watching it

C:\> ipconfig /displaydns

**dumps the DNS cache, targets that have been recently resolved (may or may not be in the same network)

C:\> arp -a

**dumps the ARP Cache, so that should be boxes on the same subnet as the box you are on

**check to see if anything is in the hosts file, hardcoded IP to DNS

C:\> net use \\[target] [password] /u:[user]

**smb session

C:\> net use * \\[targetip]\[share] [password] /u:[user]

**attaches to the next available file share, you can also specify a drive letter

C:\> net user \\[targetip] /del or net use & /del

**can only have one SMB session with a given target machine as one USERNAME at a time, so you have to delete and so you can delete them all when done

FOR /L Loops --counters

C:\> for /L %i in ([start], [step], [stop]) do [command]

C:\> for /L %i in (1,1,255) do echo %i

**simple counter

C:\> for /L %i in (1,1,255) do echo %i & ping -n 5 127.0.0.1

**pauses 5 seconds between each iteration by using the ping command

**to do more than one command [command1] & [command2]
**run command1 and only run command2 if command1 succeeds [command1] && [command2]

C:\> for /L %i in (1,1,255) do @echo %i & @ping -n 5 127.0.0.1 > nul

**@ = dont display the command

** send errors to file [command] 2>>errorfile.txt

C:\> for /L %i in (1,1,255) do @ping -n 1 10.10.10.%i | find "Reply"

**ping sweeper

nslookup [IPaddr]
**reverse lookup

C:\> for /L %i in (1,1,255) do @echo 10.10.10.%i: & @nslookup 10.10.10.%i 2>nul | find "Name"

**displays successful reverse lookups

C:\> for /L %i in (1,1,255) do @echo 10.10.10.%i: & @nslookup 10.10.10.%i 2>nul | find "Name" && echo 10.10.10.%i

**shows IP and hostname if found

FOR /F Loops --files, strings, a file set's contents

C:\> for /f %i in (password.lst) do @echo %i & @net use \\[target_IP_addr] %i /u:[UserName] 2>nul && echo UserName: %i >>success.txt

** check slides for more examples

**scripting, .bat files

**you have to do double %% in bat files

C:\> for /L %i in (1,1,100) do @echo %i

**turns into

for /L %%i in (1,1,100) do @echo %%i
