    machines deleted from the main Upstream WSUS server


      Hi everyone,


      Is there anyone here experienced or encounter the same scenario we encountered?  We have Upstream server and replica downstream servers, and we accidentally deleted all the machines from the main Upstream server, not knowing that all this machines appearing on the main Upstream servers are the ones reporting to the downstream WSUS server.  Since all machines are now deleted, they are slowly reporting back to the WSUS server but under UNASSIGNED computer group.  Is there anyway to restore the group membership as well, like if we are going to restore the backup of the main Upstream WSUS server?  My point is that deletion of machines was done on the Upstream, whether restoring it will able to help as well?  All your advise and inputs are highly appreciated.

          I'm not aware of an easy way to restore that relationship to a WSUS Target group.


          Tangential, but it might be of interest:

          There are a couple of different ways you can get machines added to the proper patching groups in WSUS.


          The way you describe above (Server Side Targeting) is the default where you point machines to the WSUS server via Group Policy and when they initially check-in to their WSUS server they are placed in the Unassigned Computers group.  You can leave them there or you can then move them to a different patching group.


          With the other way (Client Side Targeting) it is possible to configure your machines with a Group Policy that automatically assigns the machines to a specific WSUS Target Group (so you might have a different GPO for each OU if you want them to go to different patching groups).  If you use that method, then you usually just have to set up the GPOs once and then whenever you add new machines to their proper OU it can throw them in the right patching group.
