Integrated Windows Authentication Error

Jan 19, 2009 at 5:04 PM
When using Integrated Windows authentication and I click on the upload button, a username/password dialog window comes up.  I put in valid credentials, but IE freezes and I eventually have to Ctrl-Alt-Delete to shut down IE.

1.  I don't want the dialog window to appear. I have given the Network Service account full control, so the user shouldn't have to login.  How can I fix this?
2.  When IE freezes, is this a known issue?  Is there a hotfix for this?

I am using IE 7.0, IIS 6.0, Windows 2003 Server.

Thank you,

Unfortuatelly Flash does not allow to change request headers during the file upload, event though it allows for other requests, so I cannot fix this internally but you can check this thread as these guys seem to find some kind of solution:

I tried their solution, but it doesn't work when using a vanity domain or trying to save the files to a shared drive or even a mapped drive.  I keep getting prompted for a username and password.  I understand the issue with Flash, however I am confused, because when I enter valid crenditials, IE 7 locks up.  I've even tried giving "Everyone" full control on the upload folder, but I get the same issue.

Any other ideas?

“I'm experiencing the same problem as ckang.  I think the solution in the thread above must be a security glitch and only works if you reference the server name in your URL.  I've spent a lot of time on this and I am hoping there is an answer for using this control with Window authentication.”
