If I run ntpdate from client against new server I get error

	"no server suitable for synchronization found"

If I run ntpdate against another older server it has no problems and
instantly changes the time and shows the drift.

Old server is running RH 7.3 with ntpd 4.1.1 at 1.786
New Server Centos 4.3 with ntpd 4.2.0a at 1.1190-r

I have disbaled iptables and selinux but with no joy - can anyone
suggest what I can try next.

Nmap for udp:123 says its there and waiting
