Peter extracts the SIDs list from Windows 2000 Server machine using the hacking tool "SIDExtractor". Here is the output of the SIDs: From the above list identify the user account with System…

John's SID does not end with RID 500, so the account does not hold built-in System Administrator privileges.

Rebecca's SID does not carry the -500 RID suffix that designates the Windows built-in Administrator account.

Sheela's SID lacks the -500 RID, confirming the account is a standard user without built-in Administrator privileges.

Shawn's SID does not end in -500 and therefore does not represent the built-in Administrator account.

Somia's SID does not carry RID 500 and is not the built-in Administrator account.

Windows Security Identifiers use a well-known RID of 500 exclusively for the built-in Administrator account; among the listed users, Chang's SID ends in -500, uniquely identifying it as the account with System Administrator privileges regardless of what the account is renamed to.

Micah's SID does not end with the -500 RID that uniquely identifies the Windows built-in Administrator.
