Hostname does not appear by command ping -a

In my environment 20% of  machines including desktops/laptops and servers are not showing their hostname by  "ping -a  IP"  command however  i m able to get the hostname from other machines by same command.

Do all you systems are within the same subnet?
Do all you systems are configured identically for DNS?

Are all systems atleast windows 2000?

1. yes they are in same subnet (172.20.x.x) but on different VLANs
2. yes they have same kind of DNS configuration which other have those successfullly showing their hostname with same command.
3. All of my systems are in XP, VISTA, windows 7, windows server 2003 and 2008.

4. yes they all are in same active directory domain

Our network team creates new VLANs without our information so i just curious to know "does these new VLANs automatically appear in reverse zone once machine joins the domain or we need to create them manuallly ??

SGrossmannCommented:
Sorry for the late reply.

If the new VLAN is inside an existing reverse zone you don't need to add it.
If it is outside the existing zones you need to create the reverse zone manually.
