vworkspace webaccess fails

Hi,

now I have an error, when I want to connect to my virtual desktops.

I can connect to the webacces server.

But when I click on the icon of my resource, the following error occures:

A connection attempt failed because the connected party did not properly ...

When the desktop is not powered up, following is diplayed before the error:

The computer is powering up

The computer is loading os

In the log file of the connection broker there is an entry whenever I try to connect:

MPM> Execute Command Select DmStorageServers ...

MPM> Result:

MPM> Get servername, port, siloid failed

Maybe somebody has an idea?
