Using ClientNames for ItemLevel filters with Terminal Sessions

Hi all

We have about 70 thin clients in our network. We use devices names NComputing VSpace. We use itwith Terminal Services. We run Windows Server 2008 R2 as an operating system.

I would like to create a new Item Level Filter - to create and delete printers for certain devices - but I am struggling a bit with the Session Names and the ClientNames.

Here is an example of a few sessions:

At the first session: NC-VSpace#1 the ClientName isNCC-12185338-0@91854

The last part after the '@' keeps changing.

I would like to use the ClientName in the ItemLevel Filtering. So which part of the ClientName do I use? (I thought the underlined part should be used. I have created a filter, but it does not work when I use the underlined part)

Can anyone please help me with this?

Thanks
