error in creating a desktop clout

Hi,

I installed vWorkspace in easy mode in a Hyper-V-Guest. So my admin station is a virtual machine. It's part of domain questtest. The hyper-v-host is also part of this domain.

Now I want to create a new desktop cloud on my Hyper-V-Host.

I have a Hyper-V Windows 7 client on which I installed the pntools and the instant provisioning tools. I also executed the desktop optimization.

The Windows 7 Template is part of the domain questtest.

I can create a desktop cloud and the desktops are started creating. But the create process hangs with the message unknown status.

The parent vhd is copied to the vworkspace template folder. At least for the first time. After the first failure, I deleted the contents of the template store.

New desktop clouds don't copy the hyper-v template any longer.

I think the main problem is a message in the application event log of microsoft which occured also at the first attempt:

faulting application: pnbrksvc.exe

at the same time there is a crash log entry of the connection broker, which is automatically restarted
