hi there. i read and added to this thread , but maybe because it is already marked as answered, it got overlooked. basically, using the mentioned sql query, i was able to determine which pc is giving me that error. the thing is, it's just one of the clients on the lan, no different from any other client on the lan. why would i need to enable agent proxy on a plain old client pc? this pc seems otherwise normal. thx!

Hello shmengie,This message can occur when the agent proxy option is not enabled for domain controllers, cluster nodes or Exchange servers. If you do not want to change this security setting, or if you do not need to discover connection objects, disable the AD Remote Topology discovery rule by using an override.
