Our app is No Touched Deployed from a web server.

We leave the default Anonymous Access set on the web site.

So far, 4+ client installs, no problems.

I did an install on a client's web server last week, leaving Anonymous
Access checked. I did some tests, all worked fine.

Today, the app is crashing. I asked the client what's different on the web
server. Per the client they can't leave anonymous access enabled so they
unchecked it.

So, now I am seeing 401 Returns Codes in the IIS log file for our files.

How do folks work around this? It's a 2000 server box so this client cannot
create another web site. I have no idea how to how to 'log in' to the web
site when the client is making a request for a file.
