Rejoin computer to domain powershell3/30/2023 ![]() It is much more difficult to implement domain unjoining and deleting computer account from AD upon instance termination as Windows does not support On-Shutdown trigger in the Task Scheduler. Joining an AD domain, whether native or managed, could be achieved by placing a PowerShell script that performs domain joining into the User Data section of the EC2 instance launch configuration. Extensive logging to facilitate troubleshooting if something does not work as expected. ![]() Following the best practices for protecting sensitive information – the identity of the account that is used for joining domain or removing computer account from the domain.Automatic unjoining from the AD Domain and removal from AD the respective computer account when the instance is stopped or terminated.Seamless AD Domain joining when the new instances join the fleet and it should work both for Managed and native ADs.This automated solution to manage domain membership of dynamic fleet of Amazon EC2 instances should provide for: This scenario requires automated solution for managing domain membership. In either case, the fleet becomes very dynamic, and can expand and shrink multiple times to match the load or in response to some events, which makes manual management of AD Domain membership impractical. Similarly, processing nodes could be combined into scalability groups or created on-demand as a set of A mazon EC2 Spot Instances. When these workloads are moved to the cloud, it is natural to set up WEB and API farms as scalability groups to allow for scaling up and scaling down membership to optimize cost while meeting the performance requirements. However, these changes are slow and can be easily managed. When some machines are periodically recycled, respective AD computer accounts are disabled or deleted, and new accounts are added when new machines are added to the domain. When the farms and set of processing nodes are static, which is typical for on-premises deployments, managing domain membership is simple – new instances join the AD Domain and stay there. These workloads may include WEB and API farms, and a fleet of processing nodes, which typically depend on AD Domain membership for access to shared resources, such as file shares and SQL Server databases. The last step is to reboot the computer and logon with your domain credentials.This post is written by Alex Zarenin, Senior AWS Solution Architect, Microsoft Tech.įor most companies, a move of Microsoft workloads to AWS starts with “lift and shift” where existing workloads are moved from the on-premises data centers to the cloud. You will be prompted for the domain user’s password. Reset-ComputerMachinePassword -Credential -Server Then open PowerShell with elevated privileges and run the following command: To reset the computer account via PowerShell 3.0 or newer, you will need to logon to the affected computer as a local administrator. Right-click on the computer account and select Reset Account. To reset the computer account through the ADUC console, open the ADUC console and find the computer account. There are two ways to accomplish this – 1) Through the Active Directory Users and Computers console, or 2) With PowerShell 3.0 or newer on the affected computer (logged on as a local administrator). The best method to resolve the trust relationship error is to reset the computer account in Active Directory – just like you would for a user account password. ![]() By doing this you may lose all configuration information for this computer that is stored within Active Directory, as well as leave behind orphaned references to the computer account all across Active Directory. The first reaction may be to simply rejoin the computer to the domain – but this can have serious consequences, especially if this is a server. There are two ways to resolve this issue, but the easy way is not always the best. When this happens, you’re not able to log on to the computer with a domain user account. There are a few reasons why this error may occur, but in any case, there is a password mismatch between the client computer and its computer account in Active Directory. Occasionally a workstation, or sometimes even a member server, will give the error “The trust relationship between this workstation and the primary domain failed” when logging on to the computer.
