ping

i'm running ubuntu 12.04.3 x86 desktop in my corporation environment. I join the corp domain by Likewise open. But when I ping another pc, say hostname is pc-test, "ping pc-test" or "ping pc-test.domain.name" returns slow interval (about 5 seconds) but the ping value is below 1 ms. When I use "ping -n pc-test", everything works well. So I conclude this is about reverse DNS issue.

how to fix this issue? many thanks!

Edit: In my understanding, reverse DNS issue is related to DNS server or Wins server, not only an ubuntu issue, is this right?

if I wanna fix this issue as much as possible on ubuntu but not on network servers, what to do?
