Hello I am new to this site and I am in need of help. When I try to log on I type in my user name and password I get an error message that says I should check that my user name and domain are correct and then retype my password.I was told I could get in two ways type Administrator and then password or my normal user name and passwotd. I have not changed anything but it will not let me in using any combination. I have a copy of the windows 2000 pro disk but when I put it in it does not do anything. Please help I have tried everything I know
