im on a network and im trying to enumerate user accounts that already logged into some machine

i already tried to get some info with dumpsec , userdump , getacct , enum , nat ,

damn no way always access denied and i already established a null session connection

net use \\xxx.xxx.xxx.xxx\ipc$ /user:"" ""
