更新如上設定是針對windows server 2008
若OS為WINDOWS Server 2008 R2需使用如下方式
方式如下:
After speaking with Microsoft Product Support, we resolved the issue by performing the following steps to generate a new certificate with an expiry one (1) year in the future.
1) Open Services.msc and go to the Hyper-V Virtual Machine Management service and stop the service.
2) Next go to Start - Run and enter MMC - Ok
3) In the MMC go to File - Add/Remove Snap-in, in the list of Available snap-ins select Certificates then Add.
4) In the next window select Service Account and Next. In the Select Computer select the default of Local Computer then Next.
5) Now under the Service Account drill down to the Hyper-V Virtual Machine Management and select it then Finish and OK.
6) Now in the left hand pane expand Certificates, vmms\Personal and highlight Certificates. In the right hand pane double click on the certificate, should show the Issued To as the host machine name.
7) On the General tab of the certificate at the bottom it should show Valid from and a starting and ending date.
8) Closed the window for the certificate and then in the right hand pane right click and select delete.
9) Go back to the Services.msc and restart the Hyper-V Virtual Machine Management service.
10) Back to the MMC console and refresh the Personal\Certificates and you should see a new one there. Double click on it and verify the new valid dates.
11) To be able to access the VM's now you will either have to restart the VM or simply use the save state then start the VM back up.
Thanks to Ashish in Microsoft Product Support for his help.
