DNS error with Discovery

pz7rx8 — Sat, 16 Apr 2011 01:14:19 GMT

I'm running SIM 6.2. When I run a Discovery and enter the ip address the job runs but reports minor errors "...However, the forward DNS lookup was not successful because HP SIM could not get the fully qualified domain name for the system being discovered..." If I try nslookup from the CMS server both forward and reverse lookups resolve fine. Also, if I select the server and run Identify System the name resolves fine. So, how do I get the initial discovery to resolve the name ?

I would try an ipconfig /flushdns on the CMS server and followed by an identify system.

In bigger environments check the domain search option. nslookup MyCMS and Ip -> Nodename gives you something like MyCMS.mydomain.com
nslookup MyCMS.mydomain.com should you tell the same adress and more important the hostname should be also the same name.

Sometime you can get very strange response if the system has multiple NIC's.

The multiple nics seems to be the culprit. I set up the other nics with the same DNS entries and everthing is wokin fine now.
