ADCE – Local User Account Management


This feature enables the systems administrators to create a new Local User Account Management on domain computers and to manage the Local User Account Management password. The Local User Account Management Management feature can be configured using the Administrative Template file that is provided with the software.

In a typical scenario, the IT Security Policy demands that the Built-In Administrator Account default name is renamed and its password complies with the strict password policy ( typically, complex password with 8 to 14 characters that is changed every 60 days ) and is well secured.  SYNERGIX AD Client Extensions software Built-In Administrator Account Managementfeature addresses this challenge.

Additionally, the Local User Account Management Management feature can be enabled to setup a backdoor account for restricted use by systems administrators.  Managing the password(s) of the Built-In Administrator account and of the Local User Account Management on thousands of domain computers can become an overwhelming task.  Systems Administrators may choose one common password across all computers and maintain an Excel spreadsheet or a database containing unique password for each computer.  SYNERGIX AD Client Extensions offer a feature that seamlessly integrates with Active Directory environment and without requiring an external database.

The software generates unique and complex password string of length 8 to 48 characters for each computer and stores the encrypted value in Active Directory that can be retrieved by designated administrators only.  The scope of administration is managed by using an Active Directory Security group.  For example a security group SYNERGIX ADCE Managed Computers may be provisioned for this purpose.  The security group contains the domain computer accounts ( of computers installed with the software ) and systems administrators’ domain accounts that must be allowed to retrieve password.  Password are retrieve using the Admin Tools menu option in the same SYNERGIX AD Client Extensions software.


This article provides instructions on testing the SYNERGIX AD Client Extensions software.  The Local User Account Management Password Management feature is configured using the Administrative Template.  After installing the Administrative Template file, the policy setting can be found under COMPUTER CONFIGURATION \ Administrative Templates \ SYNERGIX AD Client Extensions \ Local Users and Groups \ Local User Account Management Management. The Explain tab of the Group Policy setting provides online instructions on configuring the feature.
