NWCONFIG-X-240: Volume name cannot be locked because another process is using it. Volume configuration cannot proceed.
Source: NWCONFIG.NLM
Explanation: Another process or NLM is using the volume.
Action: Wait to see if the process releases the device then retry the action. If there is a disk device error, unload NLM programs (except device drivers) that might be using the disk and dismount volumes from the disk. If these efforts fail, try loading MONITOR, deleting all user connections, and disabling logins.
