Dynamic DNS not Working
Hi all
I have Red Hat Enterprise Linux ES release 4 (Nahant) with 2.6.9-5.ELsmp kernel. I have configured Dynamic DNS.
but my clients are unable to register to my dns server.
some times it gets updated automatically but some times it gives error.
when the clients get ip for the first time(Windows 2k professional and Windows XP), they are unable to ping
to my mailserver it says unknown host, but when they do ipconfig/release and ipconfig/renew, they are able to ping to my mailserver.
my mailserver hostname is mailsrv01.msdpl.com
i get the following eror
