That is the http authentication. You need the capture url to do form
authentication <http://httrack.kauler.com/help/Authentication> and remember to
filter out the log out url.

You log out and then capture the logging in.

Searching the form you'll find that IP V6 does not work. Most suggestions is
to force Vista back to v4.

You might instead of capture url, copy your browser's cookies.txt to the
mirror and for go the capture.  Works on most sites, but not all.
