https://community.intel.com/t5/Intel-Business-Client-Software/GetEndpointReference-not-working/m-p/859437#M2200 <P>The GetEndpointReference function in WSManClient.cs (C#) will not work for CIM objects of certain types. For example, I'm trying to get/set the active system defense policy. I can use Enumerate(typeof(AMT_NetworkPortSystemDefensePolicy)), which will return up to 2 CIM objects (one for wired and one for wireless). However, if I try using GetEndpointReference on one of these objects, I get this error: "Unable to cast object of type 'MOF_CLASSES.EndpointReferenceType' to type 'System.String'." This is a problem since I can't update/delete a specific instance withoutits EPR. So if I wanted to change the active policy on the wired interface, I wouldn't be able to do so.<BR /><BR />AMT_NetworkPortSystemDefensePolicy has Antecedent and Dependent as its fields (both of type EndpointReference). Since the fieldcontanis an object andnot a value that canbe converted to a string, GetEndpointReference fails. Is there a solution to this problem? Or is there another way to do what I'm trying to do?</P> Thu, 09 Jul 2009 16:13:01 GMT Stephen_Hibbert__Int 2009-07-09T16:13:01Z https://community.intel.com/t5/Intel-Business-Client-Software/GetEndpointReference-not-working/m-p/859437#M2200 <P>The GetEndpointReference function in WSManClient.cs (C#) will not work for CIM objects of certain types.

We are contacting our development team to investigate further.</P> Thu, 09 Jul 2009 18:58:13 GMT https://community.intel.com/t5/Intel-Business-Client-Software/GetEndpointReference-not-working/m-p/859438#M2201 Gael_H_Intel 2009-07-09T18:58:13Z
