Discovery Failed: VNI-4026: Discovery failed: Error while transfer**URGENT*

Question

Hi Fellows,
I had a server with one database only. It was discovered and running fine in OEM using Oracle Management Server. I created one more database in this server and created a service. Now I can see this database when I use OEM with stand alone option. But when I try OEM Oracle Management Server and I try to discover new database, it gives me the following error:
Discovery Failed: VNI-4026: Discovery failed: Error while transferring services.ora
I ping agent and it is okay. I checked the status of Listner which is fine too. If listner is not fine I should not be able to connect.
Note: the database which I already had on the server is working absolutely fine.
Any help will be highly appreciated.
Thanks

Hi,
I was out of office yesterday. Sorry for the link.
Here is the content of that link:
goal: How to confirm DNS hostname resolution
fact: Generic Platform
fix:
1. Find the hostname of the box:
     % hostname
2. Perform nslookup on hostname
     % nslookup <hostname>
     Type in the hostname exactly as it is displayed in step 1
     nslookup returns 4 or more lines of information in this format:
          Server: <hostname.domain of the dns server>
          Address: <ip address for the dns server>
          Name: <hostname.domain for this box>
          Address: <ip address for this box>
3. Perform nslookup on host IP address
     % nslookup <ip addr>
     Use the ip address found on the 4th line in step 2
     Exactly the same lines of info as in step 2 should be returned
4. Perform nslookup on host name of target system
     % nslookup <hostname>
     Exactly the same 4 lines should be returned as though nslookup were done on
the other box
5. Perform nslookup on IP address of target system
     % nslookup <ip addr>
     Exactly the same 4 lines should be returned as though nslookup were done on
the other box
