Hi All Gurus,

I have setup an instance on Vmware Linux RHEL 4 hosting on windows. DB-
OS- RHEL 5 Update 5
Network-type - Bridged
Host -HP Desktop box with 3.5 GB RAM, Windows XP Professional, ( Pretty slow when VMware hosts were started)

I could work successfully in replicating/cloning the instance to three nodes and setup oracle streams between three instances. I could only access the terminals between each instances inside Linux Desktop/terminal as the network type was chosen bridged.
Inorder to make it accessible from host(windows) I had to switch the network to NAT and could ping and access the guest hosts from outside VM i.e on windows.
I am able to tnsping each other and listener is running fine, But while trying to connect to scott/tiger_at_host1 from host2 OR scott/tiger_at_host2from host1 is having a big trouble and facing the below issue. Could anyone
please help and advice if you had faced similar issues?

SQL> conn scott/tiger_at_host1;
ORA-12514: TNS:listener does not currently know of service requested in connect

    TNS-12564: TNS:connection refused
    ns secondary err code: 0
    nt main err code: 0

    nt OS err code: 0
I hope the issue lies in perhaps LISTENER is too fast than OS and unable to spawn a new process and physically running out of resources causing the timeout.
