The Microsoft® Exchange Server Analyzer Tool reads the following registry branch to determine if the CheckConnectorRestrictions registry value is present and configured:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Resvc\Parameters
If the Exchange Server Analyzer finds the value for CheckConnectorRestrictions present and set to 1, a warning is displayed.
If you need to apply a distribution list-based restriction to a connector, you must manually enable the checking process for these restrictions. Restriction checking is controlled by the CheckConnectorRestrictions registry value that must be set on the Exchange bridgehead server that is the source for the connector that is being checked. If you specify a restriction, but do not create the CheckConnectorRestrictions registry value, the restriction is not checked.
Connector restriction checking is turned off by default because expanding distribution groups and checking the restrictions for each message that passes through the system can significantly impact performance. If possible, enable this setting only where it is necessary (for example, on the bridgehead server for the restricted connector).
