Set-ADDefaultDomainPasswordPolicy
Synopsis
Description
The Identity parameter specifies the domain whose default password policy you want modify. You can identify a domain by its Distinguished Name (DN), GUID, Security Identifier (SID), DNS domain name, or NETBIOS name. You can also set the parameter to an ADDomain object variable, or pass an ADDomain object through the pipeline to the Identity parameter. For example, you can use the Get-ADDomain cmdlet to retrieve a domain object and then pass the object through the pipeline to the Set-ADDomainDefaultPasswordPolicy cmdlet.
