Environment

Cause

Configuration of mime types and correct path to the file must be made

Resolution

  1. Make sure Microsoft .Net 2.0 is not installed as this will cause the above error message. We did not support Microsoft .Net 2.0 until the 1.74 release.
  2. Check to make sure that on the machine that the browser is being run from has the NetBIOS over TCP/IP enabled. This can be found in the advanced properties of the TCP/IP settings on that machine.
  3. Make sure that “Directory Browsing” is enabled for the NewGraphicsFiles in the IIS configuration. This can be found by running the IIS Service manager and expanding the explorer until you see the NewGraphicsFiles virtual directory. Right-click on the virtual directory and select properties. There will be a checkbox for “Directory Browsing” in the middle of the page, make sure this is selected.
  4. On XP add the aspnet to the DNWACServerFactory folder security tab on the folder.
