This started per https://bugzilla.samba.org/show_bug.cgi?id=8872#c4 and avoids any possible collision with a different process. We also need to ensure that across a Samba installation on a single node that id.vnn is the same. Samba4 previously used 0, while Samba3 used NONCLUSTER_VNN. When a message is sent between these 'different' nodes, the error NT_STATUS_INVALID_DEVICE_REQUEST is raised. Andrew Bartlett
