>Hi Everyone,
>I have a client with a webserver running Win2000 Server. He has a WestWind Web Connect program which works perfectly until a user tries to download a file. Then they get a Windows security window. He can't figure out how to set security (and what user to set it for) so that downloads are available to all people using the site.

The odds are that the user is running in the context of IUSR_MachineName, and that account (which is used by anonymous Internet connections) doesn't have adequate privileges. Make sure that this account has read rights in the download directory; you'll need to probably grant permissions to this account in the domain, not just in the local server.

I presume this is IIS5; is the domain operating in mixed mode supporting both NT and Win2K Servers, or is it a pure Active Directory environment? You might try enabling auditing, so that you have a log entry detailing exactly caused Windows authentication to fail for the user when the download fails.
