4964: Special groups have been assigned to a new logon

On this page

For this event to be produced, auditing for SpecialGroups must first be set up. See Event 4908 for setup.

A new feature for Vista and Win2008, Special Groups auditing lets the administrator find out when a member of a certain group logs on to the computer. When an administrator sets a list of group security identifiers (SIDs) in the registry anyone in a Special Group will produce this event when logging on.
