I created a new wsus server on my network and now I can't get clients to connect correctly. All of my clients show their hostname in the wsus console, but no ip address, OS just shows Windows 0.0, and last status report is "Not yet reported". When I try to run windows update on a client, I get error 0x8024401c.
I've been through a couple of the guides from WAM ( https://www.ajtek.ca/wsus/client-machines-not-reporting-to-wsus-properly/ & https://www.ajtek.ca/wsus/reset-windows-update-gpo-settings/ ) but am still having trouble. In fact, the computers I tried these scripts on stopped reporting even their hostname to wsus.
One thing to note is that I was able to download the .cab file but can't browse to the Client.asmx page, even from localhost.
I've verified GPO settings. GPO was using a DNS pointer instead of actual server name, so I changed that to the actual fqdn, but it hasn't helped.
