502 Bad Gateway error when trying to download a file from my local web server

This is weird.  When clicking on a link to download a file on a local web server (one on our lan) and the file resides on the web server itself, I get:
 "CGI Error  The specified CGI application misbehaved by not returning a complete set of http headers. The headers are:  (nothing listed)"
When I sniffed the packets the http code was a "502 bad gateway error"
After looking this up, it mentions things about gateway/proxy.  This server does neither of those functions, and the file I am trying to download is on the same server that IIS5.0 is running on.  Permissions to this file have not changed and it worked a week ago.  

Help!!

Hi:

According to the Internet Errors and FAQs :
http://www.griffin.peachnet.edu/oit/wwwfaqs.htm#502

---------------------
502 - Bad gateway - A server (not necessarily a Web server) is acting as a gateway (or a type of routing device) to fulfill the request by the client (e.g. your Web browser) to access the requested Web page. An invalid response was received from an upstream server it accessed to fulfill the request. This usually does not mean that the upstream server is down (no response to the gateway), but rather that the upstream server and the gateway do not agree on the protocol for exchanging data. Given that Internet protocols are quite clear, it often means that one or both machines have been incorrectly or incompletely programmed.
The first thing to try when you receive this error is simply to wait a few minutes and try again.  If you are unsuccessful the second time there is nothing you can do other than to contact the person responsible for the website to let them know that you received the error.

I am the one responsible for the web site.  IIS 5.0, the file I am trying to download, and the web page files themselves are all on the same box.  There is no redirect at all for this link.
Confused.

Hi,

do you have an cgi handeling your downloads and do you have read/write rights for the directory the cgi ?

if so, try just plain html for the download and see if that works.

The past weeks there where several security patches and fixes, maybe you have installed them and the are influensing your websites behavior?

Sorry!!  Somtimes I get too focused and forget to thank whoever helped.  The suggestions you provided were correct.  I did not have the correct permissions granted to the directory.  After I set that up, everything worked great!!

Sorry again!

Thanks so much for your help.
