I did not set up our wsus server but it has been running just fine for several years until very recently. it was grabbing a bunch of updates and became stuck. i let it run for a while before canceling it out then applying the updates.. after it had installed updates the server needed rebooting which i did. server came back online just fine and all seemed good until i tried to load wsus. it seems to stick at loading, when you click on synchronization it stays at zero. after about 3 minutes, it will flash up a screen that it cannot connect to the wsus server, reset server node or copy to clipboard. i started the sql manager and can connect to the internal microsoft sql database.forgot to mention, this wsus in on this server computer.. all on same computer.
