: Why does my IIS virtual directory serve folders but not files? I have a network share (say, mysitemyshare) being served by an IIS 7.5 virtual directory at (say) http://www.example.com/myshare.

I have a network share (say, mysitemyshare) being served by an IIS 7.5 virtual
directory at (say) www.example.com/myshare. From a web browser, I can click & navigate every folder and subfolder, but if I click any file, I get a 404 error (404.0):

2015-04-10 14:27:36 GET /myshare/folder1/42-19740409.jpg - - 11.22.33.44 HTTP/1.1
Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:37.0)+Gecko/20100101+Firefox/37.0 www.example.com/myshare/folder1/ 404 1437


Here is the corresponding log entry for browsing the folder, which succeeds:

2015-04-10 14:27:34 GET /myshare/folder1/ - - 11.22.33.44 HTTP/1.1
Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:37.0)+Gecko/20100101+Firefox/37.0 www.example.com/myshare/ 200 1225


The permissions on the network share seem fine. IIS is mounting the share as user "mynetworkshareguy", and I can manually mount the share with these credentials and access all files and folders. There is also an application pool for mynetworkshareguy.

My MIME Types setup seems OK too. There are tons of MIME types set up, including for .jpg files (my example above).

I also tried right-clicking on the virtual directory in IIS, then choosing "Manage Virtual Directory" and "Browse." I can browse all the folders via localhost in this manner, but again, every file produces a 404. But strangely, the error message shows Logon Method and Logon User as "anonymous." I would think it should say "shareguy".

Module: IIS Web Core
Notification: MapRequestHandler
Handler: StaticFile
Error Code: 0x80070002
Requested URL: localhost:80/...
Physical Path mysharemyfolder...
Logon Method: Anonymous
Logon User: Anonymous


Why would all folders be accessible but none of the files? Thanks for any insights!
