Cannot login to backend using IE9 (SF 5.0)

When I try to login to the backend using Firefox or Chrome it works fine but I haven't been able to login using IE9 yet.

Everytime I try to login I remain on the login page.
I might receive the message
"Someone is already using this username and password from another computer or browser.
To proceed, you need to log him/her off"
but even clicking OK redirects me to the Login page.
Trying to Access any resource confirms me that I am still unauthenticated.

Below is the comparison of the HTTP requests between IE and other browsers.

POST /Sitefinity/Authenticate/SWT?realm....
GET /Sitefinity?wrap_deflated=true&wrap_access_token=....
GET /Sitefinity
GET /Sitefinity/Authenticate/SWT?realm=...

Firefox & Chrome:
POST /Sitefinity/Authenticate/SWT?realm....
GET /Sitefinity?wrap_deflated=true&wrap_access_token=....
GET /Sitefinity
GET /Sitefinity/Dashboard

I wasn't able to reproduce the situation. Try logging in with Firefox or Chrome and then click the "Logout" link, reload Sitefinity and then try again with IE.

Maybe something is just stuck. :D

I have done that. 
I also removed all the cookies from IE, restarted IIS and tried to login...

Is there some logs I can check to know why the authentication failed ?

I found something interesting.

If I try to login using in IE when sitefinity is running through SitefinityProjectManager internal web site (http:localhost://16258:....) , it works.

However, when i access sitefinity through the website created in IIS 7.5 ( http://MySite/.... with the hosts file containing MySite) then it fails. 

Both work with Firefox/Chrome.

EDIT: IE also works if I create a web app inside the Default Web Site.

Any idea why ?

I have the same problem updating from 4.2 to 4.3.

This behaviour is really strange as if your site was configured correctly in IIS you should be able to log in / log out correctly. Can you confirm that you have configured IIS and Sitefinity correctly to our documentation:

Also please verify that you re not logged in from some other instance in the site ( for example PM ). If you have configured your site to use IIS, stop all PM processes.

All the best,
