That could be a case of either a code problem or database corruption.
I see from another note that you are on V6 on Tru64. Some problems of
that sort are corrected at each maintenance level. Also you might see
some inconsistent behavior if you have RFI enabled, if the network has
been flagged Unreachable, since node colors are not changed in
networks and segments that are unreachable.

Now, in your specific example, you got a node symbol to change from
yellow to red. I would never expect to see a yellow node symbol in a
network or segment submap, unless someone actively changed the
status source of that symbol from symbol or object to compound.  Yellow
nodes only appear at the IP Internet level of the map, or in a Location
icon, which is a subset of the IP Internet level and has the same
properties. And then a demandpoll would not change it to red unless
all of the interfaces had turned red as well. Is there a chance that you
have
been doing some questionable cut/copy/pasting? What is proper is
documented in the Admin guide. A lot is covered there, but in real
life, all you usually need to do, ever, is to cut networks and routers
(from THIS submap) and paste them into Location icons that you
created on the IP Internet level or inside other Location icons. If you
stick to that, you should not get into any trouble.

If corruption of this sort has been introduced, it is simply corrected
by deleting and discovering the questionable nodes.

Thanks for the reply Leslie.

I did find that a node with four interfaces where two are up (green) and
two are down (red) was yellow. In your explanation you would expect it
to be red or green. Any ideas why it would be yellow? I did a demand
poll command and the node symbol changed from yellow to red.

Good question. The key to understanding symbol color at the network
and segment level is understanding that a node, in a given network or
segment, has status from the point of view of that network or segment.
That is, a device with two interfaces, one up and one down, will be red in
the network on which it has a down interface, and green in the network
on which it has an up interface. Yet at the top level map, it will be
yellow.
And the node submap, the one that shows its cards, will have one red
and one green card, regardless of how you navigated to that submap.

The color of a segment or network symbol depends on the interfaces
on that segment. They have a status source of compound. The
status source of the node symbols in those network and segment
submaps will be symbol, so that it can be programmatically set by
ipmap depending on which network or segment submap you are in.

How is the colour calculated for the symbols under the segment level
submaps for a node? I used the describe symbol command and found the
symbol status source is set to symbol. The Administrator's manual
describes how compound status works but I can't find how Netview
calculates the status for a symbol source.

I see different results. For example. One node symbol is yellow and
explodes to four interface symbols where two are red and two are green.
Another node symbol is red and explodes to two interface symbols where
one is red and one is green.
