Separate WSUS server and SCCM is set to sync updates from wsus through port 8531. If we try and access the WSUS from the SCCM server (http://wsusservername:8530/iuident.cab or 8531) Access denied or HTTP STATUS 404 not found from the SCCM server logs. WSUS server syncs without issue, should we just change the SCCM server to receive updates from Microsoft for now until resolved?
