S-1-5-32-577: RDS Management Servers
SID Decoder and Well-Known SIDs: Decode a Windows SID (S-1-5-32-544, objectSid hex or Base64, Entra ID S-1-12-1) and look up every well-known SID: Administrators, SYSTEM, Domain Admins…
Paste a SID from a permission list, an event log, whoami /all or a registry key (S-1-5-32-544), or an
objectSid in hex or Base64 from an LDAP tool, and see what each part means, which well-known account or group it is,
and its other forms. Entra ID SIDs (S-1-12-1-…) are turned back into the object ID, and an object ID into its SID.
Domain SIDs you paste are decoded on this page and not put in its address. SIDs and names are Microsoft's
(Security identifiers); the explanations are ours.
