powershell - How can I clone a GroupOfNames Active Directory Object? -

i'm writing script take 1 groupofnames object , create second group first groups members. seems simple piece of code:

$obj = get-adobject -server "$server" -searchbase $searchbase -filter "name -eq '$groupname'" -properties member new-adobject -server "$server" -path $searchbase -type 'groupofnames' -name "$newgroupname" -otherattributes @{'member'= ($($obj.member))} 

when run $obj gets created , can display both groupofnames information, list of members. when calls new-adobject cmdlet, following error:

new-adobject : unable contact server. may because server not exist, down, or not have active directory web services running. 

i've tried multiple variations of code , fail similar errors.

interestingly, if loop through list of members , add them group 1 @ time, works, takes way long (an hour+ vs seconds).

try this, casts results of first query, adpropertyvaluecollection, string array(untested!):

$obj = get-adobject -server "$server" -searchbase $searchbase      -filter "name -eq '$groupname'" -properties member $m = [string[]]$obj.member new-adobject -server "$server" -path $searchbase -type 'groupofnames'      -name "$newgroupname" -otherattributes @{'member'= $m}
