Yeah, I think you misunderstood. I must not have been clear.
Getting to the Client Settings page is easy. (I cheat and Search for HCL BigFix Client Settings).
The problem is that under the “_BESClient_RelaySelect_FailoverRelayList” setting entry on the page, it has a link that purports to take you to the “document on relay affiliation” but that link points to IBM.com rather than the HCL version of the document.
