ScriptShare

This script fixes the windows CIS Benchmark check 18.5.8: "Ensure 'MSS: (PerformRouterDiscovery) Allow IRDP to detect and configure Default Gateway addresses' is set to 'Disabled'."

The script modifies the registry to ensure 'MSS: (PerformRouterDiscovery) Allow IRDP to detect and configure Default Gateway addresses' is set to Disabled (value 0). It includes error handling and automatic verification of the setting.

Notes

• This script directly modifies the registry and does not use Group Policy.
• If Group Policy is managing this setting, changes may be overwritten. Consider using Group Policy for persistent changes.
