Brian,
for it to take so long, it sounds like netmon is really busy doing other
things...instead of processing your demandpoll. I could talk you through
netmon tracing, etc, but in doing so I would be replacing NetView support
and that it not my intent.
Before you call support I would check your DNS. If you do a "nslookup
<ip>" on a router that you know is not in the DNS, does it fail quickly, or
does it not come back for 30 seconds? Netmon is single threaded, I am
wondering if the routers that are not in your DNS is causing this. If
netmon is waiting for a DNS response, it would look like the CPU is not
busy ....but actually the thread is blocked.
Go through the netmon section in Chapter 10 of the User's Guide. If that
does not fix your problem, then call IBM Support. They can help you find
the problem.

Okay...so I did as you suggested with some success....I was able to do a
demand poll on the NetView server...and on another device. However, when
I
issued the demand poll to start....it would take anywhere from 2 minutes to
10 minutes before it finally came back with anything....sometimes I let it
try for up to 15 minutes before stopping the attempt. Thinking that the
server must be busy doing something else I reconfigured the SNMP polling
options to change the default "Poll to discover new nodes" from 20 minutes
to 1 per week....recycled the deamons with ovstop and ovstart. I brought
up
the Netview console, checked the status of the Network Monitor in the
gui....it was idle...so there were pretty much no Netview processes going
on. I checked the overall system processes...nothing going on there and
attempted another demand poll. It still took up to 10 minutes sometimes to
actually do the poll. Any other ideas !!
Thanks for your help by the way !!!!!
Brian

I still think you have a deamon problem...that could be a configuration
problem. You said that demand polls do not finish. I think that the
problem with demandpolls is the same as your icon problems.
You mention your routers are not in the DNS. Is your NetView server in
your DNS? You need both name lookup and reverse lookup working...or all
bets are off.
Steps I would take to see things.
1. Verify that DNS is configured properly.
2. Verify that you can snmpwalk your netview server from the netview
server
3. stop all daemons completely.
4. start all daemons completely
5. check status of all daemons to make sure they are running
5. wait 2 minutes, then try to do a demandpoll. it should succeed.. (do
the demandpoll on the symbol of the NetView server)
6 if the demandpoll does not succeed, and says it is waiting for netmon to
respond, then you should call NetView support.
--- do you have any other applications like "Cisco Works" or other snmp
software installed? They may be taking ports that NetView wants
