SID Values For Default Windows NT Installations

• Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0
• Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

SUMMARY

Many User Accounts, Local Groups, and Global Groups have a default Security Identifier (SID) or Relative Identifier (RID) value across all installations of Windows NT. These values can be displayed by using the utility Getsid.exe from the Windows NT Resource Kit.

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.
