In windows 2000 this can be set in the group/domain policy if you wish to
avoid manually editing the registry.

Hello List,

We have a small network consisting of an NT 4.0 Server with Win95, Win98
and W2k workstations connected to it. There are three versions of a
login banner popping up on these workstations and we need to standardize
to the one "official" version. We've changed the banner on the server,
but this has only changed some workstations. Most still have their old
login banner displaying. Can anyone tell me how can we push out the
changed login banner to all workstations?

I've been doing mainframe (acf2/racf) security for 10 years and just
started working on our NT environment (didn't lose the MF resonsibility,
though), so I apologize if this question is overly simplistic. Please be
kind.
