Expired certificates on Hyper-V

If you have a message that you cannot connect to the VM because the certificate is expired, the solution is here : http://social.technet.microsoft.com/Forums/en-US/winserverhyperv/thread/1a3e8f1b-379b-4569-9b39-bb568d2a7e3f/ (Thanks to Mark).

I have summarize the steps just if the link is dead :

• Stop the Hyper-V Management service
• Run mmc, add the certificates, choose "Services", and browse for Hyper-V management
• Go to Personal, delete the certificate
• Restart the Hyper-V Management service
• Check in the certificates console if you see the new certificate (Refresh)
