I have a local asp.net website use integrated windows authentication, whenever I try to open the website on local machine, I get 3 times credential prompts then failed with 401 error.
If I use anyother computer to do this, it is ok.
After I google, this Loop back check looks like the issue, only need disable it on the web server.
Disable the In Registry Editor,
1. Regedit
2. go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
3. Create Dword 32bit, name DisableLoopbackCheck, Value 1
4. Restart your computer.
