Disk Quota Support for FreeBSD Kernel

[Chaminda Indrajith]

Dear All,
I am new to FreeBSD and I need a help from you all please..

I have installed FreeBSD 6.2-RELEASE and did Binary Security Update 
from freebsd-update.

Then I have tried to rebuild the kernel with Disk Quota support, but 
kernel source was not available in my new server. I gave a try with 
sysinstall, but it failed and the following error message was 
appeared.

Warning:  Can't find the `6.2-RELEASE-p4' distribution on this FTP 
server.  You may need to visit a different server for the release you 
are trying to fetch or go to the Options menu and to set the release 
name to explicitly match what's available on ftp.freebsd.org (or set 
to "any").

Please help me to install kernel source and rebuild kernel.

Regards
Chaminda Indrajith
