I'm trying to create a script to run as a scheduled task, which will run against multiple servers and retrieve some information.

To start with, I populate the list of servers by querying AD for all servers that match a certain set of criteria, using Get-ADComputer.

The problem is, the list is returned as an object, which I can't then pass to the New-PSSession list. I have tried converting it to a comma-seperated string by doing the following:

foreach ($server in $serverlist) {$newlist += $server.Name + ","}

but this still doesn't work.

the alternative is to iterate through the list and run the various commands against each server one at a time, but my preference would be to avoid this and run them using one-to-many remoting.

UPDATE: To clarify what I want to end up being able to do is using -ComputerName $serverlist, so I want $serverlist to be a string rather than an object.

UPDATE 2: Thanks for all the suggestions. Between them and my original method I'm starting to wonder whether -ComputerName can accept a string variable? I've got varying degrees of success getting the list of computers converted to a comma separated string, but no matter how I do it I always get invalid network address.
