Hi All

For some reason I've changed authentication settings for some virtual directories directly in IIS (enabling / disabling "Basic Authentication", "Windows Authentication"...) I know, I've made mistake!
 Now I'm unable to login to https://exchangeurl/ecp. Although I'm certain that I've entered accurate username/password, I'm constantly getting the same login page with message that entered credentials are not ok. I have tried below but still no luck,

Remove-EcpVirtualDirectory -Identity "Exchange01\ecp (Default Web Site)"

New-EcpVirtualDirectory -WebSiteName "Default Web Site" -InternalUrl "https://server1.example.com/ecp

when i login to admin center, below window pop up
1
after i typed in login id and password, it shows below

Hello,

Looks like the error is 400.

Might wanna check http://pcsupport.about.com/od/findbyerrormessage/a/400error.htm for instance.

Have a look through IIS and check for any redirection.

Compare settings to OWA vdir (I assume it works).

Proxy server?

Run an IISreset (although I assume you've done it already).

In Exchange 2013 the settings are to be done on Exchange level (if you change them in IIS they will be rewritten.

Did you check for any redirection In IIS for ECP?

IIS redir ECP IIS redir ECP (2)
Make sure the checkbox for redirect is not there, like in the screenshot.
