Registry Permissions Not Inherited Properly After Securing the Registry with C2Config

ID: Q221766

The information in this article applies to:

Microsoft Windows NT Server version 4.0
Microsoft Windows NT Server version 4.0, Terminal Server Edition

SYMPTOMS

After securing the registry with C2Config, subkeys created in the HKEY_LOCAL_MACHINE\SOFTWARE, HKEY_LOCAL_MACHINE\SOFTWARE\Classes, HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft, and HKEY_LOCAL_MACHINE\SOFTWARE\Secure keys do not inherit the expected permissions.

CAUSE

C2Config sets the inherited permissions separately from the object permissions. The permissions to be set are defined in the C2RegACL.inf file, and it does not include the permissions to be inherited by subkeys.

RESOLUTION

To resolve this problem you should add the permissions to be inherited to the C2RegACL.inf file.

Example:

Section of C2RegACL.inf before modifications:


[HKEY_LOCAL_MACHINE\SOFTWARE]
BUILTIN\Administrators = FULL
CREATOR OWNER =  FULL
SYSTEM = FULL
Everyone = QV, SV, CS, ES, NT, DE, RC

Section of C2RegACL.inf after adding inherited permissions:


[HKEY_LOCAL_MACHINE\SOFTWARE]
BUILTIN\Administrators = FULL
BUILTIN\Administrators = INHERIT, FULL
CREATOR OWNER =  FULL
CREATOR OWNER =  INHERIT, FULL
SYSTEM = FULL
SYSTEM = INHERIT, FULL
Everyone = QV, SV, CS, ES, NT, DE, RC
Everyone = INHERIT, QV, SV, CS, ES, NT, DE, RC

Note the INHERIT entry in the permissions. This is the option that sets the permissions that will be inherited by subkeys.
