I have two instances of my application. On one server I can get a photo like this:Фото0139.jpg

and everything is ok. But on the other one (and I know the same photo is there) I get 404 error.

It happens only if diacritic letters are in the file name. Does anyone know solution for that problem ?

Can you tell which version of IIS and Windows are you using for each server? – Mircea Vutcovici Nov 12 '11 at 0:04
And which browser you use. – mailq Nov 12 '11 at 9:58

I had the same problem. It was settings of UrlScan ISAPI filter for me.

  • Just go to "c:\Windows\System32\inetsrv\urlscan\UrlScan.ini" file.
  • Search for "AllowHighBitCharacters" value and set this value from "0" to "1".
  • Restart IIS after saving the file.
