Revert VMWare Datacenter to the original name.

Problem Cause

The error is specific to VMWare integration and occurs when VMWare Datacenter name has been changed from the original name that was created in Citrix Studio. Renaming the object is unsupported as Citrix Studio integrate directly with VMWare object name.
