Simplifying Windows 2003 domain controller passwords

After I recently upgraded my company's Windows 2003 server to a domain controller, I encountered a problem where the company leader did not like to enter a complex password (both uppercase and lowercase letters, as well as numbers) at each logon. When I create an account for them and set a simple password, I am prompted to not set the password.

I thought that just click "Start → run", in the "Run" dialog box, type "gpedit.msc" into the "Group Policy Editor" can be modified, I did not think in the Group Policy Editor cannot be modified at all.

After several attempts, the author found a way to solve the problem, click "start → settings → control Panel → management tools → domain security Policy", enter "Default Domain security Settings", click "Windows settings → security settings → password Policy", double-click on the right side of the window "password must meet complexity requirements" item , a pop-up window pops up with the "disabled" option selected and click "OK" to restart the computer. The password length is also set here.
