Norton Live Update won't

Have a customer's computer with NAV 2003 on it... subscription paid up till
next year sometime. When he tries to run liveupdate, it hangs on
"confirming subscription status", then eventually pops up a message saying
it can't connect to the Symantec server to confirm that his subscription is
up to date. First thing I suspected was the hosts file, but there's not a
hosts file on the computer anywhere. There's lmhosts.sam and hosts.sam but
those are clean. I eventually had him download the definitons from the
Symantec site and update them that way. Then he did a full system scan and
came up with "no problems". He runs SpyBot S&D and AdAware regularly and
rarely finds anything but a few cookies. He has no problem browsing, And he
didn't have any problem getting to www.symantec.com either, come to think
of it. So that rules out my hosts file theory anyway.
Any ideas?
