hi,

thanks for your quick reply. I did try this, but now I get another error with the Invoke-Expression:

Changed the command to :

$Command = ".\CheckJavaProcesses.ps1 -arg (,$ComputerArray)"

Error now is:

Invoke-Expression : Missing expression after unary operator ','

If I try to call the script without buliding the command first I get:

The argument is null or empty. Supply an argument that is not null or empty and then try the command again

I am probably being obtuse here, so apologies for that
