Windows Privilege Escalation - Tools Missing on Target Machines

I’m currently doing the Windows Privilege Escalation module and am stuck on the second question in the “Communication With Processes” section. Presumably, you’re supposed to use pipelist.exe and accesschk.exe to find the pipe and display the relevant information, as they were discussed earlier in the lesson. However, when I run either of these the target machine acts as though they’re not installed. I can’t install them because I have no network connection in rdp.


I can run icacls on the target pipe but it gives me an error that says “all pipe instances are busy.” Am I missing something? Do I need to terminate all processes using the named pipe and use icacls to find the answer? Should accesschk and pipelist be installed on the target machines? Any input is appreciated. Thank you.
