It is VERY IMPORTANT that you actually post the values for the
meta-variables. It is there that the actual REASON for the failure is
specified. You also need to check the DB2 log for possibly related errors.

Otherwise it could be any of the following, and a lot more besides:
- wrong machine
- wrong address
- wrong port
- wrong or mismatched protocol
- DNS misconfiguratio n
- no DB2 started

Also what do you mean "try to connect with telnet"? What does telnet have to
do with DB2 client - server communication?

maybe you need to run the following command on your db2 instance (the
server side)

check whether you have TCPIP listed as the communication protocol or
not? run the following command from the db2 instance owners shell
prompt:
db2set db2comm

if not, then type the following command to set it:
db2set db2comm=TCPIP

once done, then check your problem again. if not solved, then do a
db2stop followed by db2start and then try again.

if this does'nt help, then probably something else is causing this, you
need to post more information then.
