[isalist] Error 502 in browsed site

I am running into a problem that appears to be well documented, but I am
not having any success in getting it to work.  I have a user going to a
"critical" (sigh) site that is causing ISA 2006 EE to throw a 502 error
to them, and in logging it shows: The HTTP message includes an
unsupported header or an unsupported combination of headers. (12156) .
I have found KBs regarding this error, the most pertinent seeming to be
935693.  I have downloaded and installed the "ISA Server 2006
Supportability Update package", which indicates that is addresses this
issue.  I also have applied the registry changes that are indicated in
935693.  Unfortunately, the error persists.  I am wondering if a reboot
or services restart is necessary after the registry change, but the
article doesn't indicate one way or other (I will try that after hours).

I understand that, at its core, this a problem with the site they are
visiting.  However, I have no realistic way to get this addressed on
that end, and the client wants it fixed now.  Is there anything that I
am missing, or any pointers anyone can provide?
