Stop User Credentials Dialogue

[Richard]

Hi All,

I have a web app on our intranet, and when an employee goes to the main
page, it authenticates via Windows Authentication when the user fills in the
user credentials dialog popup. I grab their name from wp.Identity.Name
(WindowsPrincipal), and look the user up in a SQL Server database table. So
far, so good.

They make it to the main page, but virtually every other page they navigate
to the user credentials dialog pops up again. All they do is click
linkbuttons that navigate to another page using
Response.Redirect("Page2.aspx", False). Even if they fill in the dialog
correctly, it keeps prompting them up to 3 times, then errors out (no
discernible error message).

However, when I log in as myself using their computer, I have no problems
using the app. The app initially prompts me like them with the user
credentials dialog, but once I fill it out it doesn't pop up again. So, why
would it keep prompting them?

If it helps, here are the authentication/authorization settings in the
web.config file:
<authentication mode="Windows"/>
<identity impersonate="true"/>
<authorization>
<deny users="?" />
</authorization>

Thank you for any help you can provide.
Richard

I believe I solved my own problem. I commented out '<identity
impersonate="true"/>' in web.config and it seems to be working fine. Hope
this was it for sure!
