Event ID 1003 (DHCP ) in server2003 DC.

I have two server2003 Domain Controllers. this warring appeared after I changed the network  properties (TCP/ IP )for the DC backup server (IP was static and I made it obtain IP address automatically).
I did that because  the Reservation  IP was (inactive) in DHCP.

Now in DHCP IP reservation its active,but in the event viewer I found this warning:
Event ID: 1003
Source       DHCP
Type       Warning
Description       Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address <MAC address>. The following error occured:
The semaphore timeout period has expired. Your computer will continue to try and obtain an address on its own from the network address {DHCP} server.
Note that in  the primary DC the  IP reservation address also inactive ( I didn't change anything for this DC)

So, what should I do to solve this problem?

you can reactivate the scope using the buttons on the mmc snap-in.  It's probably not recommended to have your DNS server-- or any server for that matter-- using DHCP.  The MS networking stack likes having the IP address the same from boot to boot so the services dont act up.

DNS, DHCP servers and domain controllers should have static IP. They should not be DHCP clients.

Now I returned the previous setting for the network  TCP/IP (static IP) in backup DC. will this solve the problem or should I add other step.

fetch - what do you mean by activate the scope using the buttons on the mmc snap-in.
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Restart backup DC, for all services to restart and re-register proper records in DNS and check event log again.

I restarted the backup DC, also I checked the event log its OK now.
in the DNS I changed nothing because  The IP for Backup DC is right.

could you please explain this : "re-register proper records in DNS "?  do you mean delete it and re-create  it again even if its right.

Nope, nothing to delete, if proper A (host) record is registered in DNS.
Usually you have to use "ipconfig /registerdns" to re-register host record after IP change, and restart netlogon service to propery register SRV records which are essential for AD domain environment. I've suggested restart, because it's easier. ;)
