OWA EXCHWEB Directory Resetting Permissions to integrated (ISA KCD used)

[Bmack500]

We have an enterprise ISA KCD OWA configuration to a farm of front end
OWA servers, in a front end backend configuration.
This is for CAC card authentication, and we have no problem with that.
However, when somebody clicks the "Logoff" button the page is not
found.

I have to reset the permissions on the /Exchweb/Bin directory and re-
add anonymous. It keeps losing it, and I can't find where in AD or
Exchange it's coming from.

I've tried setting it at the /exchweb level,

So if you restart the server, or the System Attendant & IIS, boom!
Anonymous is gone.
We are using a domain account for our anonymous account. Not sure if
it's relevant, but we also use Tumbleweed.

I have the KB920209 patch installed, and of course Exchange 2003 is
completely patched and up to date; native domain & forest.

I've followed the KB883380 directions, no good. I'm completely at a
loss. Authenticated users have the appropriate rights, as far as I can
tell.

How can I make the permissions on the /Exchweb/Bin directory stick?
The default web site is set at Anonymous, and of course per KCD the /
exchange, Exadmin, and Public directories are set to Integrated.

Any help would be greatly appreciated!!!

Pardon me for replying to myself, but the title should have read that
it resets the /exchweb/bin to "Basic" authentication and loses
Anonymous.

Well, I've created a discrete entry in the IIS Metabase which has
resolved this.
