* i have checked the servers ip address it is same as 18.104.22.168. what to do?
I don't have much experience on window 2000 platform, but at first you might want to make sure listener.ora file is correct, I would use Oracle Network assistant to re-create that file. If there is still problem, you might want to set up the tracing and looka at the trace file form more clues.
