MORE INFORMATION

The following information was taken from a Domain Controller named DomainName. The default groups differ on a Windows NT Workstation or Server installation, and if they are not a member of a domain, then the computer name would be considered the authority.

The values below that have a full SID value will differ on all installations, but the RID value at the end of the SID is the same across all installations.

NOTE: The values in parentheses is the hexadecimal values of the RID.
