Error When Reviewing Unassigned Computers RRS feed

  • Question

  • Good morning.  I'm running WSUS on a fully-patched Win 12 R2 server.  The "Computers" server is a downstream server running the WID database.  When I click on the Unassigned Computers group, I get an "Unexpected Error".  The error is at the end of this post.  There's a corresponding 7053 error in the Application event log. All other computer groups work fine.

    It doesn't matter from which computer I try to access this group. I get the same error.  No other downstream server has this problem.

    I have rebooted this downstream server. I have removed the "wsus" mmc settings from the appdata folder.  I'm thinking that this is something in the database itself.  I'm seriously considering starting with a new database.

    Any help is much appreciated.
