Third Wall provides two policies to help you manage the assigned Administrator password.  The Set Local Administrator Password and TWAPS (Third Wall Administrator Password System) will by default only manage the built-in, original Administrator account.  With Third Wall version 2.5.4.5 and up, the target may be altered.

To do this, add a registry entry to the computer(s) under policy.  Add a REG_SZ entry to HKLM\Software\LabTech\Plugins\ThirdWall\store named 'AdminNameOverride'. The value should be the name of the local account you want managed:

This command will add the registry key for you.  Be sure to change 'ThirdWallmin' to the name of your choice:

REG ADD HKLM\SOFTWARE\LabTech\Plugins\ThirdWall\store /v AdminNameOverride /t REG_SZ /d "ThirdWallmin" /f 

This will not work on Domain Accounts, the alternative user name must be a local user name already existing on the target computer.  If the assigned username does not exist, a ticket will be issued, alerting you of the issue.

With this registry setting in place, once either the Set Local Administrator Password or TWAPS policy is enabled on the computer, the policy will monitor the account named by this registry change.
