Error when attempting to move AD-User

Question

Receiving error :" Move-ADObject : The operation could not be performed because the object's parent is either uninstantiated or deleted"
My Script:
import-module activedirectory
import-csv c:\mylist.csv |
    foreach-object{
        $user=Get-AdUser $_.userid
        $dn=$user.distinguishedname
        $parent=([adsi]"LDAP://$dn").Parent.Replace('LDAP://','')
        $newdn="OU=disabled accounts,$parent"
        $newdn -replace "OU=Temporary Accounts,",  ""
        $user | Disable-ADAccount
        $user | Move-ADObject -targetpath $newdn -targetserver mgw-2k3-dc1.xyz.com
So I tried  specifying a -targetserver, I receive error:
Move-ADObject : Can't move objects with memberships across domain boundaries as on
ce moved, this would violate the membership conditions of the account group. Remov
e the object from any account group memberships and retry
I'm assuming I'll have to query for the DC they reside on and make that the target for each object?

Answer 1

If I try and add a -targetserver myserver-2k3-dc1.xyz.com to : 
 $user | Move-ADObject -targetpath $newdn 
i receive: 
Move-ADObject : Can't move objects with memberships across domain boundaries as once moved, this would violate the membership conditions of the account group. Remove the object from any account group memberships and retry
...which sort of blows my mind. Not sure if this is helpful or not. Just wanted to add
