I had given up on this on another thread, but decided to post again because I've gathered a bit more information now and hopefully someone can point me in the right direction.
I have a Windows SBS 2008 server that recently had WSUS 3.0 SP1 reinstalled. I created the GPO's per Microsoft's instructions, created the computer groups, etc. and the Updates section of the SBS Console is a pretty green color. That said, it's not working still. When I open WSUS to approve updates or look at updates/computers, there are no computers listed in the groups - zero. When I try to update (for example, on the server) I get the error "8024400E" and it says it cannot check for updates. There is little to no help online for this error.
I did some more digging and found the error in the windowsupdate.log. Also, I ran Microsoft's Client Diagnostic tool, which failed. I've attached the latest portion of the log file, and a screenshot of the ClientDiag.exe tool.
I'm assuming if I can fix it for the server, I can fix it for the other clients as well. Any help would be fantastic.
Note: The server name of "fox1", local domain is "foxbc", and the WSUS is set to run on port 8530.
