Install-ADServiceAccount

Install-ADServiceAccount is accessible with the help of addsadministration module. To install addsadministration on your system please refer to this link.

Installs an Active Directory managed service account on a computer or caches a group managed service account on a computer.

The Install-ADServiceAccount cmdlet installs an existing Active Directory managed service account (MSA) on the computer on which the cmdlet is run. This cmdlet verifies that the computer is eligible to host the MSA. The cmdlet also makes the required changes locally so that the MSA password can be managed without requiring any user action.

The Identity parameter specifies the Active Directory MSA to install. You can identify a MSA by its distinguished name Members (DN), GUID, security identifier (SID) or Security Accounts Manager (SAM) account name. You can also set the parameter to a MSA object variable, such as $ or pass a MSA object through the pipeline to the Identity parameter. For example, you can use Get-ADServiceAccount to get a MSA object and then pass the object through the pipeline to the Install-ADServiceAccount.

The AccountPassword parameter allows you to pass a SecureString that contains the password of a standalone MSA and is ignored for group MSAs. Alternatively you can use PromptForPassword switch parameter to be prompted for the standalone MSA password. You need to enter the password of a standalone MSA if you want to install an account that you have pre-provisioned early on. This is required when you are installing a standalone MSA on a server located on a segmented network (site) with no access to writable DCs but only RODCs (e.g. perimeter network or DMZ). In this case you should create the standalone MSA, link it with the appropriate computer account and assign a well-known password that needs to be passed when installing the standalone MSA on the server on the RODC-only site with no access to writable DCs. If you pass both AccountPassword and PromptForPassword parameters the AccountPassword parameter takes precedence.

-AccountPassword 
         The AccountPassword SecureString parameter will allow you to inline pass-in the password of a standalone Managed Service Account (MSA) that you have pre-provisioned early on and is ignored for group MSAs. This is required when you are installing a standalone MSA on a server located on a segmented network (site) with no access to writable DCs but only RODCs (e.g. perimeter network or DMZ). In this case you should create the standalone MSA, link it with the appropriate computer account and assign a well-known password that needs to be passed when installing the standalone MSA on the server on the RODC-only site with no access to writable DCs. If you pass both AccountPassword and PromptForPassword parameters the AccountPassword parameter takes precedence.
