Hyper-V is set to 'not initialized' vworkspace 7.5

hello,

I am trying the new version on vworkspce 7.5 in lab environment and was running fine till i modified the Master Image and tried to reprovision Desktop with updates. althought update were not applied after all Computer delete but Hyper-V were also set to 'Not initialised' state and could not find the cause for it. i thought i goofed up some thing so i decided to create new Cloud Computer Group but it dint helped me at all.

I Rebooted the Hyper-V server, installed Broker Helper Service but nothing helped.  i could also not find any information for such case when Hyper-V is not initializing.

Error which i got is attached below

although i can see Volume information avaiable in the console.

thanks for help in advance..

Regards,
