Cisco ISE disabled all internal Network users

Question

Hi All,
Somehow, this morning when we checked on the ISE, all the IP phone users along with the internal users are disabled. We have disabled the password policy to disable the accounts if password is not changed. Our version is 1.2 and no patches. Can anyone please advise on this.
Wireless authentication for users against AD is ok.
Thanks

Requiring Guests to Change Password
You can allow or require guest users to change their password after their initial account credentials are created by the sponsor. If guest users change their passwords, sponsors cannot provide guests with their login credentials if they are lost. The sponsor must create a new guest account.
You can either allow guests to change their passwords, or you can require that they do it at expiration and at first login. To require internal users using a guest portal to change their password upon their next login, choose Administration > Identity Management > Identities > Users . Select the specific internal user from the Network Access Users list and enable the change password check box.
Before You Begin
Create a Guest portal or modify the DefaultGuestPortal. This setting is specific to each Guest portal.
Step 1 Choose Administration > Web Portal Management > Settings > Guest > Multi-Portal Configuration.
Step 2 Check the Guest portal to update and click Edit .
Step 3 Click the Operations tab.
Step 4 Check either or both options:
Allow guest users to change password
Require guest users to change password at expiration and first login
Step 5 Click Save .
