$Serverslist=DXXXX1W9262,DXXXX1W9261 is incorrect PowerShell syntax.

If you use $Serverslist='DXXXX1W9262', 'DXXXX1W9261', the command should work fine, because $Serverlist is an array containing two strings. If you use $Serverslist='DXXXX1W9262,DXXXX1W9261', then this is only one string that is not parsable as an instance name.
