Cannot Sync WSUS

When I attempt to perform the initial synchronization on a freshly installed OS I get the following error in the Application event log:

Synchronization failed. Reason: The underlying connection was closed: Could not establish secure channel for SSL/TLS..

Google search turns up nothing...

Any ideas?

To clarify what is failing, the replicacion of WSUS with Windows Update OR the download of updates from your WSUS to a computer/server.

Post the number of the event error you find in Event Viewer.

Did you turn off IE enhanced security configuration?  I think that kills the WSUS sync.
