Which method will allow you to trace all ever-established user accounts on a Windows 2000 server over its lifetime?

• A. Review of SIDs in the Registry
• B. Forensic duplication of hard drive
• C. Analysis of volatile data
• D. Comparison of MD5 checksums

Answer: (A)

On Windows, every user account is tied to a unique security identifier (SID). The system keeps a record of user profiles associated with those SIDs in the Registry, specifically under the ProfileList area. This Registry location lists each SID that has had a profile on the machine and stores details like the profile path. Importantly, entries for deleted or removed accounts often remain in this part of the Registry, at least for a period, providing a historical trace of all accounts that were ever established on the server. By examining these SID entries, you can reconstruct the full set of accounts that has logged in over the server’s lifetime, even if the accounts themselves have since been deleted. Other methods don’t provide this lasting account-history capability: duplicating a hard drive copies data but doesn’t highlight the historical presence of accounts; volatile data is lost after shutdown or reboot; and MD5 checksums don’t reveal user account histories.
