This sounds like an issue where you have $cookie_domain set in settings.php but are accessing the site via a different domain. Make sure that cookie domain is set correctly and that you are using the exact same domain to access it via Windows.

hi,
I've setup a drupal 7.12 on a Debian squeeze box and I have a strange issue. I log on the drupal site with no problem with any browser on a linux and mac OS X box. But I can't log on with any browser on a windows os. Each time I enter the login / password, the system don't logon with no errors at all, Just displaying the home page again.
Any ideas.
Olivier.
