Server slow after install vWorkspace RDSH

Hi,

I have a clean installed (physical) server. After the installation of the terminal server role of vWorkspace the server is extremely slow.

I had multiple times that the explorer hangs...

When i delete vWorkspace from the server everything is ok again.

I did a check with network monitor and i see that when vWorkspace is installed the explorer does a call to my connection broker... When vWorkspace is not installed anymore there are not calls registered in my network monitoring

what can it be?
