Hi all,

I got to thinking about how this process could potentially be abused and
it occurred to me that anyone that was allowing external access to their
default web site was now allowing external folks to query for the
internal ISA configuration.  Needless to say, I found this just a bit
distasteful.

I thought about creating steps to validate ISA policies, etc., but I
quickly realized that this was a potential rats-nest if anyone had more
than one rule or they were using packet filters (ISA 2000) or access
rules (ISA 2004) to publish web sites.

What I decided to do was control it at the source.  I've added steps to
the "file modification" sections that will address this question and
help you keep your internal information internal.

The updated package is available at http://isatools.org/sbs_wpad_2.zip.
As always, comments, questions, small unmarked bills are welcome.

Jim,

Did you get the email I sent privately regarding WPAD? Just wondering
because I've had difficulty emailing you before.

Thanks,
