SummaryPermanent link for this heading

Under some circumstances you get an error HTTP 404 when connecting to a Fabasoft Web service on Windows 2008 R2. The [Enter] page is displayed (so authentication works correctly), but the redirect to the fscvext.dll fails with HTTP 404. In IIS log you see the substatus code 404.8 - "hidden namespace of hidden segment error".
