Vmware Oracle streams issue

Hi All Gurus,
I have setup an instance on Vmware Linux RHEL 4 hosting on windows.
DB-10.2.0.1.0
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;
ERROR:
ORA-12514: TNS:listener does not currently know of service requested in
connect
descriptor

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.
