Upgrade from 2.9.1 to 3.3, dashboard fails to load

I just upgraded our install from 2.9.1 to 3.3 and everything is looking good aside from the admin dashboard. When accessing the page it goes right back to the login page. I log in, it briefly goes to the admin/dashboard page(frame is empty on right), then back to the main blog page. I setup a completely new installation with default data on the same iis instance and it works fine.

Any ideas?

To further expand on the issue. I copied our appdata over to the working install and get the same results. I assume something isn't compatible in the posts etc and it's causing the dashboard to fail with a redirect rather than an error.

Check that 'View Dashboard' rights are enabled for Administrators

Thanks goranh. That was so simple I feel pretty silly now for not catching it.
