404 errors after hotfixes

We have 2 internal web servers, identical (we thought) for all intents
and purposes. Recently we installed August hotfixes (list below) on
both boxes. On one box, all web applications in the default website
whose home directory is a relative path (created by
right-click/properties Create...) now return 404 errors. The same
applications on the second box are behaving normally. What could be
different between these boxes that we haven't seen?

Answer turned out to be simple - the home directory spec for the
default web site. One box (the broken one) included a trailing
backslash. Don't know what was in the hotfixes, but the sites worked
before but not after they were applied
