Hello guys

Actually i'm trying doing an autoregistration for our park, we work only with windows serveur so i'm trying to do an autoregistration i'm using this configuration 

Server=10...111
ServerActive=10...111

HostnameItem=system.run[powershell -noprofile -noninteractive -command "& gcim win32_computersystem -Property dnshostname,domain | foreach \{ ($_.DNSHostname + '.' + $_.Domain).ToLower() }"]

and when i'm launching it i'm getting this error
