What does a WinRC=5 Access Denied error in a CPM domain controller indicate?

The WinRC=5 Access Denied error in a CPM (Credential Provider Manager) domain controller specifically indicates that the user is not authorized to change their own password. This code suggests that there are permissions or policy settings in place that prevent the user from performing this action.

In a Windows environment, users typically require certain rights or group memberships to change their passwords successfully, particularly if they are trying to change passwords for accounts that are not their own. When this error occurs, it confirms that the user lacks the necessary permissions defined within the domain's security policy.

Other options may describe situations that could lead to complications, such as entering incorrect credentials leading to login failures or network issues causing connectivity problems, but these do not directly relate to the Access Denied classification. Additionally, the account being locked due to inactivity indicates a different type of access restriction that would not specifically generate a WinRC=5 error.
