IIS not publishing images
Strange problem I am having. I have three website servers running IIS. Two of them work fine. Each server is paired with its own separate file server that stores the images that the website looks for and publishes. The third one will give a web page but the pictures have that "missing image" look. Now, we thought it might be something wrong with the file server but the other two servers, when we change the path, are able to get images off the file server that is paired with the third IIS. We even pointed the third server to look at the other two file servers and we got the same results. Quite confusing. Any ideas?

Are all running the same version of OS?
What is the mechanism that accesses the files from the file server?
Try the following
telnet thirdiisserver 80
GET http://URL/image path/image HTTP/1.1
Host: your_hostname
Refererer:
And see what you get as a response, the item of interest is the HTTP header I.e. you might be outputting the wrong Content-Type:
This presumes that you have an ASP or some dynamic script that accesses the file share and feeds/streams the image to the user.
At times a better approach is to place a reverse proxy I front of the dynamic content such that the static images are fed from the proxy.

All three IIS servers are on 2012 R2. I don't know if I ran that correct or not but the response I got was content-type txt/html. I might have typed something wrong because there is no return echo when I type.

Here is the return I got when I put in the above. BTW was the spelling of refererer supposed to be referrer?

The response you received is an error.
Does the .net application you use the same on all three or does each have their own written app.
Look at the source on IIS server 3 for the <Img src=
The issue is either the mechanism does not allow access to the fileserver where the images are stored in this case or the output image is not properly designated as image/png etc.
Do you have an asp page that you can use that will access the fileserver share and list the names and directories within the share?
The issue is isolated to the IIS server 3 since none of the other fileservers can be accessed.
