How to disable the password expiration on Windows Server 2008

If your server is non-domain joined and you are not using Active Directory the Local Security Policy controls items like password complexity rules, account lockouts, and password expiration. To turn off password expiration you'll need admin rights and to simply edit the Local Security Policy:

• Launch “Local Security Policy”: Start > Administrative Tools > Local Security Policy
• Expand “Account Policies” and select Password Policy
• Set the Maximum Password age to “0″
