It is always recommended to create a new Admin user on the first log in and keep the MasterAdmin as the back up. If you can log in with one administrator user, you can unlock the users who have been locked out from the Deep Security Manager console.

Do the following:

1. Log in to the Deep Security Manager console using one of the working Admin users (example, MasterAdmin).
2. Go to Administration > Users.
3. Double-click the username or user that has been locked out and then deselect the Locked Out (Prevented from system sign in) check box.
4. Click Apply > OK.

If all the administrative users are locked out, you can use the following command to unlock them.

1. Open the DOS command prompt window and then go to the ..\Program Files\trend Micro\Deep security Manager directory.
2. Type in the following command:

   dsm_c -action unlockout -username USERNAME

   For example: dsm_c -action unlockout -username admin
