Name:
    GeneralPage

Description:
    Creates the eponymous property page and is used by the PropSheet object.

Notes:
	The changes you make in this won't partial immediately affect the behaviour of
	the server but only after restart. This applies to the connection parameters.
	Changes may lead to a configuration, which is inapplicable for remote administration
	or requires corresponding changes in the configuration of the remote interface
	application, particular of the PropSheet object.

Example:
	<PRE>
	&lt;Object&gt;
		Name GeneralPage
		Class GeneralPageClass
		PropertyPage GeneralPage
	&lt;/Object&gt;

	</PRE>
