All local drives is not frozen. vSphere Client server event reports, warning message from esx host: The guest OS has reported an error during quiescing. The error code was: 5 The error message was: "VssSyncStart' operation failed: Access is Denied. (0x80070005). vpxuser
This is happening to random Windows 2008R2 Servers.
Any help with solving this will be greatly appreciated!
