I've got an asp.net intranet app, and am using IIS Basic authentication for 
the site.  No anonymous access, no integrated authentication.  Credentials a
re being authenticated to local host.  The problem is that the user needs to
 authenticate three times.
Only the final username/password submission counts.  First two tries don't c
ount.  If they succeed on the third try, they're in.  If they fail, they're 
not.  Just started happening "out of the blue".  Any ideas?
