Hi All, |

|
| 3 |
I am facing problems in configuring DDNS with dhcpd. When i'm rebooting |
| 4 |
linux machine, it is getting dynamically ip address from linux server but no |
| 5 |
dynamic dns updates are there. Also when i renew ip address of windows 2000 |
| 6 |
prof, it not getting ip address from linux dhcp server. Following is the |
| 7 |
configuration that might help you solving my problem. Both Master DNS and |
| 8 |
dhcp server are on the same server server1.guru.com |
