I have 2 Solaris machine running 2 ips in same subnet 14.140.201.17 & 14.140.201.100 and they both have same gateway 14.140.201.1. Now both machines are acessible through network but they cannot ping/connect to each other. What could be the reason ? Any help is appreciated .
Thanks
two ip's in the same subnet is generally not allowed nor a good idea...
Ok but this is a test environment and i ned to transfer data between the servers. Do u have any idea what could be the issue though both servers are pingable/reachable from 14.140.201.103 & vice-versa
Could you post the output of
netstat -rnv
of both machines and 14.140.201.103
i missread your first post... you have 2 servers and each server has one ip?

one server is a virtual machine?
yep Ldom
vnet0 is on igb0 which is T3-1's main network interface
Can someone suggest on this .. the issue is stil not resolved. 
Are both servers connected to the same switch. There is a feature on some switches where machines can ping the default router but not between each other... is called port protected.
Do you have a third machine to test on the same net?
You have two machines on the same subnet that can't see each other.
What does traceroute say on each machine??
The traceroute to hostname will tell you if your DNS is working.
The output might tell you where the connection is ending up, eg. on a managed switch or something.
you can also use:
route get <ip address>
To see where are your packets going...
have you also tried with telnet to some port rather than ICMP?
