You have gained shell on a Windows host and want to find other machines to pivot to, but the rules of engagement state that you can only use tools that are already available. How could you find other machines on the target network?
1) Use the "edit" utility to read the target's HOSTS file.
2) Use the "net share" utility to see who is connected to local shared drives.
3) Use the "ping" utility in a "for" loop to sweep the network.
4) Use the "scapy" utility to automatically discover other hosts.
