I am a user researching for my admins. Since recently, I cannot connect to my Hyper-V VM with Virtual Machine Connection.
- On the first try I receive the error message "This user account cannot access the virtual machine's video."
- On the second try, the machine has vanished from the list of virtual machines and typing the name manually yields the error message "An error occured trying to find the virtual machine $vm on server $host. Cannot find virtual machine with the name $vm."
- The VM will reappear in the list ofter some time and things start again with (1.)
Other machines from the same master image fail to start with the error message "$vm failed to change state. You do not have the permission to perform the operation."
The responsible admin claims that no changes have been made to the permissions settings. It may be possible that other admins have tampered with the system though.
What unnerves me about this error is that there is only a single mentioning of this error message on the web without a viable solution.
Both servers and clients run Windows Server 2008 R2.
