Those pesky 0x8024402c WSUS errors...

If you administer WSUS you probably had this 0x8024402cerror  in WindowsUpdate.log already, right?

So, let's check together:

- no WinHTTP proxy (here)? Check!
- IIS is working fine on WSUS server? Check!
- DNS resolves servername? Check!
- GPO's are flowing nicely and you have your WSUS server defined under WUserver and WUStatusServer in  HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate? Check!

Still having this error? Go to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU and check if you have UseWUServer=1 DWORD entry. I didn't have it and it was the reason of problems, despite that GPO's were ok.

For reference I suggest this technet article.
