"Accidentally" Uninstalled WSUS. Broken Updates.

[MagnumVP]

We had an Admin that "Accidentally" uninstalled the WSUS, settings and DB from the SCCM 2012 R2 Server.

 

After reinstalling the WSUS server, settings and DB with the same settings, nothing is syncing with the SCCM 2012 R2 software updates group. When refreshing the "All Software Updates" it only shows the updates from December 2014 and nothing from January.

 

Is there a way to "re-link" SCCM with WSUS or do I have to reconfigure all the groups again from scratch?

 

The original setup of the Software Update Service were followed using the Step-By-Step guides on this site.

Do you find anything useful in the WCM.log file of ConfigMgr?

Here is what I see in the wsyncmgr.log

 

"Sync failed: WSUS server not configured. Please refer to WCM.log for configuration error details.. Source: CWSyncMgr::DoSync"

 

In the corresponding WCM.log file I see;

 

System.Security.SecurityException: Request for principal permission failed.~~ at Microsoft.UpdateServices.Administration.AdminProxy.CreateUpdateServer(Object[] args)~~ at Microsoft.SystemsManagementServer.WSUS.WSUSServer.ConnectToWSUSServer(String ServerName, Boolean UseSSL, Int32 PortNumber)~~The Zone of the assembly that failed was:~~MyComputer

I have verified that both IIS and SCCM are pointing to 8530.

Looking over these log I see some interesting errors and I'm wondering if these are erroneous errors.

 

Question. If the network is configuring ALL Workstations/Server to point to the primary SCCM server, do the remote servers/sites need to have the Software Update Point installed? Currently all remote servers/sites have a Distribution Point where the clients can pull their updates from, but do those sites need to have the WSUS installed as well?
