Please provide some details:
- How many days are left for evaluation for vCenter Server as well as the ESXi host?
- What kind of hardware (vendor/model/CPU/memory) do you use for the ESXi host?
- Attach the Windows 2008 R2 VM's vmware.log (can be downloaded using the datastore browser) to a reply post.
