ping problem !!

[kong121s]

my situation is
- I can ping full name (www.test.com) from outside server but I can't ping test.com
- I can ping both www.test.com and test.com inside my server.(use Putty)
- I can't ping mail.test.com !! but I can send mail and received mail as well.

may be coz' I changed IP address of my server and didn't fix some file.

Thank you.

I forget question. (-.-")

My question is How to fix this problem? Which file I should fix?

I config new IP by use ISPconfig > management > server > setting
and config some files:
/etc/hosts
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network
/etc/resolv.conf
DNS of all website, I removed it and recreated for each website.

I try to find the solution in this forum but not found.

Help me please. Thank you

Did you have a look here? http://www.howtoforge.com/forums/showthread.php?t=2760

Yes, I have already read that thread before I made this thread.

After I setting IP in Management > server > setting
I look for some files which contain IP Address.
some file must made a change by myself and some files are changed by ISPconfig.

ps.I use Fedora core 5 with ISPconfig 2.2.1

Did you change the DNS records for test.com and mail.test.com so that they point to your new IP?

Yes. I deleted all dns in DNS manager and then empty recycle bin.
and recreated dns in ISP Manager.
