Best Get-AdComputer Guide: Mastering PowerShell 101

In this article, we will explore the various capabilities of the Get-ADComputer cmdlet and how it can be used to query and manage computer objects in an AD environment. Join us as we delve into the world of Get-ADComputer and learn how to harness its power to effectively manage and administer computer resources in your AD infrastructure.

Simple Get-AdComputer Parameters

When using the Get-ADComputer cmdlet in PowerShell, there are several simple parameters available to customize the retrieval of computer objects from Active Directory. These parameters help you refine the search and obtain specific information about the computers. Here are some commonly used parameters:

  1. -Identity: Specifies the identity of the computer object to retrieve. You can provide a distinguished name (DN), GUID, security identifier (SID), or SAM account name.
  2. -Filter: Allows you to define a filter to retrieve computer objects based on specific criteria. It uses PowerShell’s syntax and allows you to specify conditions using attributes and comparison operators.
  3. -Properties: Specifies the properties of the computer object to retrieve. You can specify multiple properties separated by commas or use the wildcard character (*) to retrieve all properties.
  4. -SearchBase: Specifies the search base from which to begin the search for computer objects. You can provide the distinguished name (DN) of an OU or container to limit the search to a specific location in Active Directory.
  5. -SearchScope: Determines the scope of the search. It can be set to "Base" to search only the specified object, "OneLevel" to search immediate child objects, or "Subtree" to search the specified object and all its descendants.

These parameters allow you to customize the Get-ADComputer cmdlet’s behavior and retrieve computer objects based on your specific requirements. You can combine them to perform more advanced and targeted searches.

Identity Parameter

The -Identity parameter in the Get-ADComputer cmdlet is used to specify the unique identifier of the computer object you want to retrieve from Active Directory. The identifier can be the distinguished name (DN), GUID (objectGUID), security identifier (SID), or the computer’s common name (CN).

By using the -Identity parameter, you can target a specific computer and retrieve its associated information from Active Directory. This parameter allows you to search for a computer object using different identifiers, making it flexible and convenient.

Here’s an example of using the -Identity parameter in Get-ADComputer:

Get-ADComputer -Identity "CN=Computer01,OU=Computers,DC=example,DC=com"
Identity Parameter

In this example, the -Identity parameter is used to specify the computer object’s common name (CN) along with its location in the Active Directory hierarchy. This command retrieves the details of the computer object named “Computer01” located in the “Computers” organizational unit (OU) within the “example.com” domain.

Filter Parameter

The -Filter parameter in the Get-ADComputer cmdlet allows you to specify a filter to retrieve specific computer objects from Active Directory based on certain criteria. The filter uses PowerShell’s syntax and allows you to define conditions that must be met for a computer object to be included in the result set.

With the -Filter parameter, you can specify various attributes and their corresponding values to filter the computer objects. This provides flexibility in narrowing down the search results to only the desired set of computers.

Here’s an example of using the -Filter parameter in Get-ADComputer:

Get-ADComputer -Filter {OperatingSystem -like "Windows 10*"}
Filter Parameter

In this example, the -Filter parameter is used to retrieve all computer objects where the OperatingSystem attribute matches the pattern “Windows 10*”. This will return all computers running Windows 10 or its different versions.

LDAPFilter Parameter

The -LDAPFilter parameter in the Get-ADComputer cmdlet allows you to specify an LDAP filter to retrieve computer objects from Active Directory based on custom search criteria. The LDAP filter syntax follows the Lightweight Directory Access Protocol (LDAP) standard and provides advanced filtering options.

With the -LDAPFilter parameter, you have more flexibility in defining complex search conditions using LDAP filter syntax. You can specify attributes, comparison operators, and attribute values to precisely target the desired computer objects.

Here’s an example of using the -LDAPFilter parameter in Get-ADComputer:

Get-ADComputer -LDAPFilter "(operatingSystem=*Server*)"
LDAPFilter Parameter

In this example, the -LDAPFilter parameter is used to retrieve all computer objects where the operatingSystem attribute contains the word “Server”. This will return all computers with an operating system that includes the word “Server” in its value.

Locating Computers in Organizational Units

To locate computers within specific Organizational Units (OUs) in Active Directory, you can utilize PowerShell cmdlets such as Get-ADComputer with the -SearchBase parameter. The -SearchBase parameter allows you to specify the OU from which the search for computer objects should begin.

Finding Accounts on Child OUs

To retrieve accounts located in child Organizational Units (OUs) in Active Directory, you can use the -SearchScope parameter in combination with the -SearchBase parameter in PowerShell cmdlets such as Get-ADUser or Get-ADComputer.

The -SearchScope parameter defines the scope of the search and determines whether it should be limited to the base OU only or include all child OUs as well. By setting the -SearchScope parameter to "OneLevel", you can ensure that the search is restricted to the immediate child OUs.

Here’s an example of retrieving user accounts in child OUs using the Get-ADUser cmdlet:

Get-ADUser -Filter * -SearchScope OneLevel -SearchBase "OU=ChildOU,OU=ParentOU,DC=domain,DC=com"
Finding Accounts on Child OUs

In this example, the -Filter parameter is set to * to retrieve all user accounts, the -SearchScope parameter is set to "OneLevel" to limit the search to immediate child OUs, and the -SearchBase parameter is set to the distinguished name (DN) of the parent OU. Replace "OU=ChildOU,OU=ParentOU,DC=domain,DC=com" with the appropriate DN of your parent OU. Happy Browsing!
