Device names in HP SIM

Hello everyone. I apologize for posting a question to a topic that has already been addressed, but the thread was locked or I would of just added a reply to that thread.

okay, on with my question.

I'm running Systems Insight Manager 4.1 with SP1 - Windows
Here is the issue I am having. In my list of normal servers in system overview, some of my servers have host names listed others just have IP's. I have forward and reverse DNS lookup configured and I can verify by nslookups of both IP and Hostnames that resolve correctly. Why would some of my server host names show up and others do not? Can anyone point me in the correct direction?
Thanks in advance.

Do you have WINS running on your network? If so, WINS could be responding to your nslookup query.

HP SIM only uses DNS, not WINS. If DNS cannot respond to HP SIM then HP SIM doesn't get a name. There's no magic.

If your network administrator is incapable of correcting his DNS you can create a local hosts file at %WINDIR\system32\drivers\etc\hosts that will be searched first and return a name for you.

HP SIM 4.2 (available now) has an "Edit System Properties" feature that lets you directly edit the system name as recognized within SIM.

No, I do not have WINS running.

I understand how SIM "gets" the hostname. My question is why would SIM show host names for over 120 or so boxes, and not on around 50 or so more. I understand that this is probably not a SIM issue, as you have mentioned there is no "magic" involved. I was just inquiring if anyone has come across this issue and what steps they took to trouble shoot it, sometimes a fresh set of eyes, looking at the same problem can be helpful.

I want to stay away from adding host file, since there are about 50 or so servers to do. I would like the host names to update dynamically in case we decide to "recycle".

Thanks for the suggestions.

When running automatic discovery on a large number of systems, the discovery process could take a long time.

If there were an outage on the DNS server, or a networking device on the route to the DNS server, it could have prevented hp Systems Insight Manager from having access to DNS services at that time.

Try deleting one or more of the affected entries, then manually add the system(s) at a time that the DNS service has been verified to be reachable. If the problem goes away, it verifies my scenario.
