I have OMS running on Solaris 8. Also the OEM repos is in 9iR2 database on the same machine.
I have a 8.1.7 install on W2K adv server with Oracle agent service is running on it. dbsnmp process is also running. When I try to discover this node I get "Discovery failed VN-4009 : Cannot contact agent on this node. The agent may be down or network communication to the node failed." message.
The 8.1.7 install on W2K server was very standard and I didn't do anything special.
Please help.
--Nitin.

the Agent is probably not running or the hostname of the target node
is mapped to the wrong IP Address. This mapping error can occur in
the local hosts file or in your DNS server.
1. Verify the network is up by pinging the target host by hostname.
2. Verify the Intelligent Agent is running on the target host.
On UNIX: ps -ef | grep dbsnmp
On Windows NT: Use Task Manager, and check for a DBSNMP process
3. From the OMS server, verify that you can ping the hostname of the
Intelligent Agent server. If you cannot, network administrator.
Ask the Network Administrator to add the hostname of the target server
to the Domain Name Server so that forward and reverse
DNS hostname resolution is successful.
4. Restart the Intelligent Agent.
5. Run the Discovery Wizard again from the EM Console.
sometimes the host_name would be just given as machinename
eg: PROD1.
but the actuall name would be machinename.domainname.
eg: PROD1.ABCcompany.com
