Recently at work we have been trying to get an old Siemens industrial PC going. It was missing the screen but have hooked up an external monitor to it for the moment. The problem is when i turned it on it went through what i think was the windows NT setup procedure, i had to enter the owners name and make a password etc. Then it restarted and has asked for a username and password, i tried all the names and passwords i had entered previously but still no go, is there anyway around it, please help?
