We are are running IIS 6.0 on Windows Server 2003.
The problem is that it's not possible to open via web browser any document (ms-word or pdf or excel) that its name contains spanish special characters (accents). The documents are storage on a virtual directory of the IIS.
For instance, via web browser it's not possible to open this document, because the name of the file contains character "ó":
When trying to open the file, on the web browser it's displayed: "The page cannot be found"
But it is possible to open this document, which its name has no special character:
What kind of setting is missing on the IIS or Windows Server 2003? Has anyone seen this problem before?
