Sharepoint and UrlScan Tool don’t mix!
Today, after 3 weeks of (well deserved
) holiday, I noticed that I couldn’t reach my custom developped SharePoint webservice anymore on a test-environment.
After searching some time, I discovered the MS UrlScan Security Tool had been installed which blocked all calls to the webservice and simply returned a 404 because the url contained a “.” character in the path to the webservice asmx.
You’ll find numerous posts online about difficulties with UrlScan and SharePoint installed together, just don’t mix them
