BITS Problem with WSUS

["Jim G" <support@xxxxxxxxxxxxx>]

This is also a post int he Wusoep.general newsgroup. I haven't been able to 
get any answers.

Ok we are still having problems downloading updates.  If I dial up they work
fine, if I use a dsl they work fine.  I can type the URL and get through our
Proxy just fine.  I also downloaded a BITS GUI interface that allows you to
use BITS to download files.  Works fine.   What does the following error
mean below?  We are using NETCACHE 5.5R6 for our proxy.

I would like a Microsoft Tech to help on this one unless someone else knows
what the deal is.  And no its not any of the problems others have had.
