I am trying to do some pentest training on my local labs. I created a lab has 3 Windows 2012 r2 servers and 2 Windows 7 + 8 PCS. All machines protected via passwords. I added both to the domain controller then I tried to use psexec tool to connect to both via this command:
PsExec.exe \\192.168.1.22 cmd
It connected without password or user name.
Can anyone explain why this happened and why I can log in to pc's on my domain without passwords?
