Windows SID

Question

When did the SID for a Windows account (local, domain, Active Directory) change after creating an account? If so, under what conditions.

Answer 1

Yes, this may change when moving an account to a new domain.

With the attribute SidHistoryin your AD account, you can find all the previous security identifiers for this account.
