The Security Configuration Wizard creates a duplicated rule in Windows Server 2008 and in Windows Server 2008 R2 when you edit an existing rule

Consider the following scenario:

• You have a computer that is running Windows Server 2008 R2 or Windows Server 2008.
• You use the Security Configuration Wizard to change a rule by editing an existing security policy .xml file on the computer. Then, you save the file.
• You use the Security Configuration Wizard to view the changed rule. Then, you save the file.

In this scenario, the Security Configuration Wizard creates a duplicate rule for the change in the Network Security section. The wizard does not update the existing rule directly.

Note This issue occurs when the rule is a network security rule that is of the auto-generated type.

For example, you use the Security Configuration Wizard to edit a rule that is named "rule1." After you save the change and then check the rule, you find two rules that are named "rule1." One rule has the original settings, and the other rule has the changed settings.

The issue occurs because the Scw.exe utility incorrectly assigns a new unique ID to the rule when the Scw.exe utility edits the original rule. Scw.exe keeps both the original rule and the changed rule because the two rules have different unique IDs.
