Add-ADComputerServiceAccount

SYNOPSIS
Adds one or more service accounts to an Active Directory computer.

SYNTAX

Add-ADComputerServiceAccount [-Identity]  [-ServiceAccount]  
[-AuthType {Negotiate | Basic}] [-Credential ] [-Partition ] 
[-PassThru ] [-Server ] [-Confirm] 
    [-WhatIf] []

DESCRIPTION
The Add-ADComputerServiceAccount cmdlet adds one or more computer service accounts to an Active Directory
computer.

The Computer parameter specifies the Active Directory computer that will host the new service accounts. You can
identify a computer by its distinguished name (DN), GUID, security identifier (SID) or Security Accounts Manager
(SAM) account name. You can also set the Computer parameter to a computer object variable, such as
$, or pass a computer object through the pipeline to the Computer parameter. For example, you
can use the Get-ADComputer cmdlet to retrieve a computer object and then pass the object through the pipeline to
the Add-ADComputerServiceAccount cmdlet.

The ServiceAccount parameter specifies the service accounts to add. You can identify a service account by its
distinguished name (DN), GUID, Security Identifier (SID) or Security Accounts Manager (SAM) account name. You can
also specify service account object variables, such as $. If you are specifying more
than one account, use a comma-separated list.

Note: Adding a service account is a different operation than installing the service account locally.

PARAMETERS
-AuthType
Specifies the authentication method to use. Possible values for this parameter include:
Negotiate or 0
Basic or 1

The default authentication method is Negotiate.

A Secure Sockets Layer (SSL) connection is required for the Basic authentication method.

The following example shows how to set this parameter to Basic.
-AuthType Basic

The following lists the acceptable values for this parameter:

        Negotiate
         
        Basic
         
        Required?                    false
        Position?                    named
        Default value                Microsoft.ActiveDirectory.Management.AuthType.Negotiate
        Accept pipeline input?       false
        Accept wildcard characters?  false

-Credential
Specifies the user account credentials to use to perform this task. The default credentials are the
credentials of the currently logged on user unless the cmdlet is run from an Active Directory PowerShell
provider drive. If the cmdlet is run from such a provider drive, the account associated with the drive is the
default.

To specify this parameter, you can type a user name, such as "User1" or "Domain01\User01" or you can specify a
PSCredential object. If you specify a user name for this parameter, the cmdlet prompts for a password.

You can also create a PSCredential object by using a script or by using the Get-Credential cmdlet. You can
then set the Credential parameter to the PSCredential object The following example shows how to create
credentials.
$AdminCredentials = Get-Credential "Domain01\User01"

The following shows how to set the Credential parameter to these credentials.
-Credential $AdminCredentials

If the acting credentials do not have directory-level permission to perform the task, Active Directory
PowerShell returns a terminating error.

        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        

-Identity
Specifies an Active Directory computer object by providing one of the following property values. The
identifier in parentheses is the LDAP display name for the attribute.

Distinguished Name
Example: CN=SaraDavisDesktop,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
Security Identifier (objectSid)
Example: S-1-5-21-3165297888-301567370-576410423-1103
Security Accounts Manager Account Name (sAMAccountName)
Example: SaraDavisDesktop

The cmdlet searches the default naming context or partition to find the object. If the identifier given is a
DN, the partition to search will be computed from that DN. If two or more objects are found, the cmdlet
returns a non-terminating error.

This parameter can also get this object through the pipeline or you can set this parameter to a computer
object instance.

This example shows how to set the parameter to a distinguished name.
-Identity "CN=saraDavisDesktop,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com"

This example shows how to set this parameter to a computer object instance named "computerInstance".
-Identity $computerInstance

        Required?                    true
        Position?                    1
        Default value                
        Accept pipeline input?       true (ByValue)
        Accept wildcard characters?  false
        

-Partition
Specifies the distinguished name of an Active Directory partition. The distinguished name must be one of the
naming contexts on the current directory server. The cmdlet searches this partition to find the object defined
by the Identity parameter.
The following two examples show how to specify a value for this parameter.
-Partition "CN=Configuration,DC=EUROPE,DC=TEST,DC=CONTOSO,DC=COM"

-Partition "CN=Schema,CN=Configuration,DC=EUROPE,DC=TEST,DC=CONTOSO,DC=COM"

In many cases, a default value will be used for the Partition parameter if no value is specified. The rules
for determining the default value are given below. Note that rules listed first are evaluated first and once
a default value can be determined, no further rules will be evaluated.

In AD DS environments, a default value for Partition will be set in the following cases: - If the Identity
parameter is set to a distinguished name, the default value of Partition is automatically generated from this
distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is
automatically generated from the current path in the drive.
- If none of the previous cases apply, the default value of Partition will be set to the default partition
or naming context of the target domain.

In AD LDS environments, a default value for Partition will be set in the following cases:
- If the Identity parameter is set to a distinguished name, the default value of Partition is automatically
generated from this distinguished name.
- If running cmdlets from an Active Directory provider drive, the default value of Partition is
automatically generated from the current path in the drive.
- If the target AD LDS instance has a default naming context, the default value of Partition will be set to
the default naming context. To specify a default naming context for an AD LDS environment, set the
msDS-defaultNamingContext property of the Active Directory directory service agent (DSA) object (nTDSDSA) for
the AD LDS instance.
- If none of the previous cases apply, the Partition parameter will not take any default value.

        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        

-PassThru
Returns the new or modified object. By default (i.e. if -PassThru is not specified), this cmdlet does not
generate any output.

        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        

-Server
Specifies the Active Directory Domain Services instance to connect to, by providing one of the following
values for a corresponding domain name or directory server. The service may be any of the following: Active
Directory Lightweight Domain Services, Active Directory Domain Services or Active Directory Snapshot instance.
Domain name values:
Fully qualified domain name
Examples: corp.contoso.com
NetBIOS name
Example: CORP

Directory server values:
Fully qualified directory server name
Example: corp-DC12.corp.contoso.com
NetBIOS name
Example: corp-DC12
Fully qualified directory server name and port
Example: corp-DC12.corp.contoso.com:3268

The default value for the Server parameter is determined by one of the following methods in the order that
they are listed:
-By using Server value from objects passed through the pipeline.
-By using the server information associated with the Active Directory PowerShell provider drive, when
running under that drive.
-By using the domain of the computer running Powershell.

The following example shows how to specify a full qualified domain name as the parameter value.
-Server "corp.contoso.com"

        Required?                    false
        Position?                    named
        Default value                
        Accept pipeline input?       false
        Accept wildcard characters?  false
        

-ServiceAccount
Specifies one or more Active Directory service accounts. You can identify a service account by using one of
the following property values:
Distinguished Name
Example: CN=serviceadmin,CN=Europe,CN=Users,DC=corp,DC=contoso,DC=com
GUID (objectGUID)
Example: 599c3d2e-f72d-4d20-8a88-030d99495f20
