Web Service Method Returns "HTTP 404 - File Not Found"

TOPIC

The Web service's HTML description and help pages appear to work fine, however when using a web browser to invoke a specific method an "HTTP 404 - File not found" message appears.

DISCUSSION

This error condition may be caused by Microsoft's Urlscan security tool, which is designed to block specific HTTP requests. Urlscan is normally installed in "%WINDIR%/system32/inetsrv/urlscan/".

The default settings of Urlscan include an option to reject requests for URLs containing dot (".") characters, which may affect the functionality of the Currency Server Web service. You can verify that this is indeed the case by viewing the "urlscan.log" file in the Urlscan installation directory.

To solve this issue edit the "urlscan.ini" file in the Urlscan installation directory and set "AllowDotInPath=1".
