I don't have a lot of experience with the NT version, but I will take a
crack at this... First off you should
consider upgrading this system to 5.1. It is a WAY better product. Anybody
else?

The icons being reset are apparently on the IP map, so they are primarily
managed by the ipmap application so their status is by default IP-only and
set by netview. Under Edit..Modify..Map, there is a place to modify ipmap
behavior. You can tell it not to override user changes to status. Normally,
though, icons created by Netview should be left to netview to manage. Most
add-on applications that want to affect status do so by adding icons in
with
the interface cards, so the status propogates up. REad the section in the
Admin guide about status.

This sounds like a bad deal to me. I would call that a corrupted database.
If things are being added correctly to the default map, it may not be too
bad. I would delete the custom map and recreate it by doing a File..Save
of the default map. Understand the difference between a map and a submap.
A map (eg 'default') has lots of submaps. A separate, custom, map, is one
thing; adding custom submaps to the default map is another thing. It
worries
me that you say they tried to copy items between maps. I can't think how
you would do that. So if they are copying things to submaps, they are
probably not in a real good state. Net, new items should appear in all
maps automatically. If they don't, there is something wrong with the map
they don't appear in.

which

In V5.1 for NT there is a command to copy the map database from the server
to the
clients, if that is what you are talking about. In Netview for Unix, you
just need to back up the database directories by whatever means you
available.
That is, /usr/OV/databases/openview and the same directories are used for
NT.
If there is a relational database involved, well, I don't know exactly what
the implications are.
