me again :)

If you set Mandatory = $True it will never permit a $Null value for $Workgroup, and therefore never prompt.

You'd have to rip out Mandatory as well, and, since you're casting to a string, test for "" instead of $Null :)

So what you're saying Chris, is that I should just leave the answering to you? :)

My thought on the $null was that the variable was never used, but since it's cast in the parameters, it makes sense that past that point, it will need to be "".

Thanks again for the help.

It never ceases to amaze me how much I don't know about Powershell.
