I found this on page 54 of the white paper:
"Automatic Updates will not be able to contact the Microsoft Windows Update
servers on the Internet through a proxy server that requires authentication."

I found this on page 79 (the appendix):

EventID=106
Severity=Error
SymbolicName=MSG_MISSING_WWWROOT

If authentication is your problem, you might need to set up a SUS server
