This XP workstation at my work has this message whenever you start it up. I've tried going into the recovery console to try a repair but no one seems to have the admin password. When i try using Windows Key to replace the password it doesn't recognize an operating system on the C drive so it has no password to replace. However when i go into recovery console it asks for this password. How can i reinstall this file and get my system back up and running? Thank you in advance for any help you can provide!
