Like said in the intallation page in the manual at step 10, you have to enter a strong password with at least one capital letter and one number, so Passw0rd or [email protected] should do the job. When you are logged in to windows you can disable this enforment via this tutorial.
The only mistake you can make during the installation is selecting a Server Core Installation in stead of a Full Installation, but I guess this doesn’t affect the creation of a new password at the first start.
I JUST installed Server 2008 (complete installation) and am confronted with creating a new password before opening the OS. Whatever I enter is not good enough. What are the rules? Am I on the wron track if I want this for a workstation? Did I make a mistake installing the complete server rather than going the custom installation route? How should I proceed?
