I don't see confirmed that you have tried to ping both the host name and ip adress of the server. Check your DNS if you can only ping by ip adress.

Some things you can check:

-Ensure that all plugs are secured and screwed down on the adapters.
-View the status of existing adapters and interfaces (the adapter being  the physical hardware; the interface being the software that enables communication on that hardware)
-Verify that the adapter you are using is "Available".
-Check the error report: errpt -a | more
-Do an arp -a to see if the ip adress of the pc that's pinging the server is listed. If not then the packets don't even get to the server and you should indeed check your firewall logs. Maybe your firewall doesn't allow ICMP.
-Verify that your netmask is correct.
-Verify the server hostname:  hostname
-Ensure that software is loaded correctly: lppchk -v
-Verify the adapter configuration. If you see only lo0, or if there is an "*" next to your interface, you need to configure the interface again.

Let us be more direct - what changed? It used to work but it does not work now - what happened between these two states?

check for routing table configuration also. if default is not there you might face this issue. netstat -r  . check with old ruting table backup if you have.

Most of the problems coming through recent change ?

check for ip configuration and /etc/hosts entry also.

Thanks dfjke,sim and ram for your reponse.... I have found that the filesystem in that server is full and that is the reason for the huge packet drops. I have deleted some of the files and now i am able to telnet the machine.

/tmp and /usr are up 100% and /var  /root are up 90%
