I'm using ASP.NET 2.0.I have created a application with some component support written in VC++.It is a normal application which uses this ISAPI filter component for specific reasons.
This is our scenario,We display a link of a file ( example : abc.pdf ) along with its folder location id and file id.
Example Link : http://hostname/webfolder/abc.pdf&folderid=1&fileid=3
In the above link, host name where the file is resided, folder id is, in which folder it belongs and file id is which file to be accessed.
Failure Scenario, When i copy this link and paste it a new window IE browser and access it, it popups windows authentications, when we give user id and password..
Http 401.1 Error is thrown , this happens only when we install Vista SP1, when we run the same scenario without Vista SP1. It works fine.
What would be the reasons, please let me know any solutions.
Note, I have tested this scenario with windows XP,windows 2000,Windows 2003.
It works fine.Every request process through our VC++ Component ( ISAPI filter ).
I monitored for all request, with an network tool ( Windows Network Monitor 3.1).
In normal condition (without Vista SP1), it pings and request and file is shown properly.
But while Vista SP1 is installed, the request doesnt reach ISAPI filter, it request for 5 times and then this error is thrown.
