How to get Linux host name written in Windows DHCP and DNS?

Oops...I did not know about that network command...good to know!

OK..here goes:

If I run "host execlinux"? The cursor just returns with no output (if I type the same thing from another machine, I get the error you mentioned).

If I ping the IP address, I get normal returns.

If I "ping -c 5 execlinux", I get "ping: unknown host execlinux"

Why reboot? Run "service network restart" instead.

Not necessarily. That is info about the network you've put in using
system-config-network.

What happens if you run "host execlinux"? If you get something like

    [root at dragon ~]# host execlinux
    Host execlinux not found: 3(NXDOMAIN)

then the host name is not getting into DNS.

What happens when you ping the appropriate IP address? If you get
nothing back from pinging the host name (the apparent resonse here),
that suggests that the host name is set up correctly and you are
getting domain name resolution. However, you should get some sort of
complaint from ping. Try "ping -c 5". That will send five ICMP
packets, and complain if you don't get a response. e.g:

    [root at dragon ~]# ping -c 5 phoenix
    PING phoenix.localdomain (192.168.1.47) 56(84) bytes of data.
    From dragon (192.168.1.4) icmp_seq=2 Destination Host Unreachable
    From dragon (192.168.1.4) icmp_seq=3 Destination Host Unreachable
    From dragon (192.168.1.4) icmp_seq=4 Destination Host Unreachable
    From dragon (192.168.1.4) icmp_seq=5 Destination Host Unreachable

    --- phoenix.localdomain ping statistics ---
    5 packets transmitted, 0 received, +4 errors, 100% packet loss, time 3999ms
    , pipe 3

Phoenix resolved correctly, but the host is down, so it is not
reachable.
