We have seen issues if this is a Windows 2008 Server, Try the following information/configuration setting (on the vSphere Client)
Application consistent quiescing of Windows 2008 virtual machines is only available when those virtual machines are created in vSphere 4.1. Virtual machines created in vSphere 4.0 can be updated to enable application consistent quiescing by modifying a virtual machine’s enableUUID attribute.
Since application level VSS quiescing is not available in VDDK 1.1.1 (need 1.2 per the 1.2 release notes) I believe the “enableUUID” parameter is causing the quiesce to fail (thus the access rights error)
(so we need to disable the “disk.EnableUUID” feature to get this to work)
Disable Windows 2008 Virtual Machine Application Consistent Quiescing
1 Start the vSphere Client, and log in to a vCenter Server.
2 Select Virtual Machines and Templates and click the Virtual Machines tab.
3 Right‐click the Windows 2008 virtual machine for which you are enabling the disk UUID attribute, and
select Power > Power Off.
The virtual machine powers off.
4 Right‐click the virtual machine, and click Edit Settings.
5 Click the Options tab, and select the General entry in the settings column.
6 Click Configuration Parameters...
The Configuration Paramters window appears.
7 Click Add Row.
8 In the Name column, enter disk.EnableUUID.
9 In the Value column, enter FALSE.
10 Click OK and click Save.
11 Power on the virtual machine.
