I wanted to find out who made a change on a server – on a known day at a known time. Looking through event-viewer on the server all I could find was an irrelevent “TerminalServices-Printers” error. However within this error – by clicking the Details tab and expanding the ‘system’ paragraph I saw a USERID, which was a long string of numbers and dashes.
To resolve this userid I opened regedit and expanded HKEY_USERS. I located the userID in question and right-clicked it. Examininmg the ‘permissions’ configuration the username was listed.
