How to Get user info from different domain

Question

How to Get user info from different domain. Get-ADUser -Identity username work with same domain1 but i want to know user info from different child Domain

Solution

I typed Get-Help Get-ADUser -Full and found the following:

-Server <string>
    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 Director
    y 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

Is this what you're looking for??

This should really be tagged as Powershell and ActiveDirectory.

I have gone throw following syntex but i believe due to Active Directory Web Services not running it has no result (Get-ADgroupMember -Identity "DL Name" | Get-ADUser -Server "DomainA" | Set-ADUser -Manager "Manager name" ) , error that comes up (Get-ADUser " Unable to contact the server. this may be because this server no exist, it is currently down, or it does not have the active directory web services running)...

You have a logic problem in that query. You querying the current domain for Get-ADgroupMember -Identity "DL Name" the other domain for Get-ADUser -Server "DomainA" and then the first again for Set-ADUser -Manager "Manager name" ) you need to use -server for all the requests.
