Insufficient resources are available

Hi,

I have a problem with my hyper-v server and VMM 2012 SP1 CTP2. I have only one hyper-v server, no cluster. I have an error message when I'm trying to change network adapter settings on any virtual machines. I have a lot of free space and memory available. 

I reinstalled VMM, hyper-v without any changes.

Error 2911

Insufficient resources are available to complete this operation on the servername server. Not enough storage is available to complete this operation (0x8007000E)

I don't know what to do next...

Any Help ?

Thanks!
