I have spent a whole searching for some help on this but have not succeeded. Server Manager 2012 R2 has a Manageability error "Online - Data retrieval failures occurred". No Events, Services, BPA, Performance nor Roles and Features show any data.TASKS->Refresh always gives a Refresh failed error. All Servers Task Details notification reads"[Servername]: Configuration refresh failed with the following error: Invalid namespace".
I have read this post on TechNet about Server Manager Refresh Failure but it does not address my error details. No posts that I have read seem to specifically address theInvalid namespace issue.
This is a server with the WSUS role installed, Sophos AV Console. WSUS clients Windowsupdate.log show that they are successfully connecting to the service, as well as Sophos clients.
Any help would be appreciated.
