ESXi

Hello!

I run a multi-tenancy system to provide my students with virtual space for their projects, and have created a script (finally!) to do my bidding. The script reads a CSV file, then creates resource pools, vm & templates folders, datastore folders, dvportgroups (and private/community vlan pairs), and sets permissions on each. The script runs _successfully_ (in that everything is set up as expected) but it throws an error that I cannot figure out. The line in the script that causes the problem is:

Get-VDPortgroup $dvPrtGrpName | New-VIPermission -Principal $ad_grp -role $vrole

I have tried various incarnations of this:

New-VIPermission -Entity (Get-VDPortgroup $dvPrtGrpName) -Principal $ad_grp -role $vrole

and

$newdvprtgrp = (Get-VDPortgroup $dvPrtGrpName)

New-VIPermission -Entity $newdvprtgrp -Principal $ad_grp -role $vrole

but all throw up this message window:

I have searched these forums, used Google, tried various key words, etc., but have found no answers.

Does anyone have a suggestion of where to look, or what might be the problem(s)?

Thanks!
Mark

Forgot to mention that I was running the script in the Powershell ISE with all the vmware snapins when I get this message. Just tried it in the actual PowerCLI 5.8 Release 1 console and it throws no error messages.
