Snapshot removal failed: unable to access file since it is locked

Current Running environment is ESX 4.1 and Veeam 5 (running on a VM) for backups.

The current backup job never completed successfully, it simply stopped mid backup. I couldn't kill the job or do anything so I rebooted the Veeam backup server.

To finish the clean up I selected the VM that was being processed in the stuck backup and told the system to remove the snapshot.

An error message was received and the snapshot was never removed. The error message was "unable to access file since it is locked"

To completely disable IPv6 on a Windows Server 2008-based computer yourself, follow these steps:
  1. Open Registry Editor.
  2. Locate the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip6\Parameters
  3. In the details pane, click New, and then click DWORD (32-bit) Value.
  4. Type DisabledComponents, and then press ENTER.
  5. Double-click DisabledComponents, and then type 0xffffffff in Hexadecimal or 4294967295 in Decimal.

Note The 0xffffffff value or the 4294967295 value disables all IPv6 components except for the IPv6 loopback interface.
