are
considered
identical
only
if
they:
1.
Are

You
can
solve
some
problems
by
comparing
the
configuration
and
software
setups
between
working
and
nonworking
servers.
When
you
compare
servers
to
each
other
for
diagnostic
purposes,
consider
them
identical
only
if
all
the
following
factors
are
exactly
