Hi Simon

Here is my /etc/dhcpd.conf file contents

# Sample dhcpd.conf
# Sample configuration file for ISC dhcpd

ddns-update-style ad-hoc;

# option definitions common to all supported networks...
#option domain-name "virtualnode03.grid";

# Your name servers. You can normally find these in
# your /etc/resolv.conf file. These will be distributed to all DHCP
# clients.
#option domain-name-servers;

default-lease-time 600;
max-lease-time 7200;

lease-file-name "/var/lib/dhcp/dhcpd.leases";

# If this DHCP server is the official DHCP server for the local
# network, the authoritative directive should be uncommented.

# Use this to send dhcp log messages to a different log file (you also
# have to hack syslog.conf to complete the redirection).
log-facility local7;

# Configuration for an internal subnet.
subnet netmask {

                 range dynamic-bootp;
 #option domain-name-servers;
 #option domain-name "virtualnode03.grid";
 option routers;
 option broadcast-address;
 default-lease-time 600;
 max-lease-time 7200;

Also my ifconfig looks like this

[root at g40 ~]# ifconfig eth0
eth0      Link encap:Ethernet  HWaddr 00:0F:FE:3B:10:18
         inet addr:  Bcast:  Mask:
         inet6 addr: fe80::20f:feff:fe3b:1018/64 Scope:Link
         RX packets:369 errors:0 dropped:0 overruns:0 frame:0
         TX packets:1416 errors:0 dropped:0 overruns:0 carrier:0
         collisions:0 txqueuelen:0
         RX bytes:33241 (32.4 KiB)  TX bytes:82265 (80.3 KiB)

In /etc/dhcpd.conf  I haven't configured the option
domain-name-servers . Is this must for dhcp server configuration??

Please help me to sort out this issue.. Still Im getting the same no
free leases error.. What is the root cause for this no free leases
