Fixed server roles are defined at the server level and have permissions to perform specific server-level administrative activities. Fixed server roles cannot be added, removed, or changed.

To add or removed members from server roles, see ALTER SERVER ROLE (Transact-SQL).

All logins are a member of public. sp_helpsrvrole does not recognize the public role because, internally, SQL Server does not implement public as a role.

Requires membership in the public role.
