LVR groups issue, script issue

reverting back to the command converting LVR groups... Having a slight issue and I am wondering if you can look at this script and provide input.

$groups = Get-content $("c:\users\user_name\lvrgroups.txt")
Foreach ( $group in $groups ){
@(dsget group "$group" -members | dsmod group "$group" -chmbr)}

recieve error concerning
dsget failed:A referral was returned from the server.
type dsget /? for help.dsmod failed:The parameter is incorrect.
type dsmod /? for help.dsget failed:A referral was returned from the server.

This is a CN group naming context.
CN=Z,OU=Y,OU=X,OU=FEDKX-UC,OU=UC,DC=company,DC=local
