I currently have 1 upstream server and 3 downstream servers. I recently noticed that my upstream server and 2 of my downstream servers show 0 updates installed on the Overview page, yet the clients themselves when selected in WSUS show installed updates. Any idea how to recalculate the Overview page? I have tried to restart WSUS and the Server cleanup wizard but no luck. Not sure why the 1 server is correct either.

Hi,

Have you tried to remove all of the clients from the server then wait the clients contact the server again?

Sorry I was on vacation.. No that did not work, I have tried that with several clients but can not seem to get them to show on the Summary page..

Hi Marty,

Please try to remove all the clients and let them to connect the WSUS again.

If some clients failed to report their status, this issue may occur.

I found a similar thread which explained it clearly:
