Vulnerability discussion

Computer account passwords are changed automatically on a regular basis. Enabling this policy to disable automatic password changes can make the system more vulnerable to malicious access. Frequent password changes can be a significant safeguard for your system. If this policy is disabled, a new password for the computer account will be generated every 30 days.
