I have an IIS7 webserver with webdav. I have a secure site and an application under that site that points at the UNC path of my fileserver (https://site.edu/student). Basic Auth and Anonymous Auth are enabled.
If I try to open a webdav folder (a subfolder of my application path https://site.edu/student/accountname The basic auth challenge comes up and sometimes it will work just fine. Other times I type in the correct credentials and it comes back. After challenging me 3 times is gives up and asks if I would like to see its default view instead. It's completely random as well. Some times I can get in the first time. Sometimes it will ask me once and fail, then I'll wait 30 seconds, type in my credentials again and it will work. Sometimes it won't work at all no matter how many times I try.
I've tried creating a new app pool and assigning it to the application; even giving the app pool a domain admin account as the identity as suggested here: http://forums.iis.net/t/1152391.aspx but it behaves the same way
Any ideas?
Much appreciated
