I have been having VMware 5.5.0 Snapshot errors using Netbackup 188.8.131.52. NetBackup job error 156. Failed to quiesce the virtual machine. 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!
