Simple Server 2008/IIS 7.0 fully patched setup with index.htm file listing mp4 videos. Because of client data safeguards I have Digest Authentication in place. When a domain user accesses from the outside, they are prompted for their user name and password. The index.htm page displays and the domain user clicks on a mp4 video. The problem is the "Enter Network Password" box challenge comes up for every mp4 video on the index.htm web page. This happens with Windows 7 running Internet Explorer 10 and XP running Internet Explorer 8. If I use an iPad 3 and the Safari browser, I enter my user name and password once to access the index.htm and I am allowed to view all videos without the "Enter Network Password" challenge box popping up.

Hi, Thank you for the post. As this issue is more about IIS, you may post this thread in this forum:http://forums.iis.net/ Regards, Nick Gu - MSFT
