I had a slow loging box before (maybe 1-2 minutes) and was just an old version of EEPC, upgrading to next point release at the time fixed it for me.
What version are you running?
I am having the SAME exact problem.
I am in the middle of installing McAfee Drive Encryption on 400+ laptops and once this is done I will be moving to Desktops. However, 2 laptops are starting to have issues. In the beginning they worked fine, but for some odd reason, they are starting to hang during boot up. The laptops average around 10 minutes before the login dialog box loads. During this time the keyboard and mouse are completely unresponsive. Once it loads the user is able to enter there information without any issues and load into Windows. I have attempted to completely remove Drive encryption by decrypting the drive and uninstalling the software. I rebooted and confirmed the product was removed. I reinstalled the software and encrypted the drive again but once I rebooted, the laptop hung at the encryption startup for 10 minutes before loading the login window.
Is there anything I can do about this? Please help!
