Event Id 1002 - DHCPNack Message

I am getting the following error when i try to assign IP (Through DHCP Server) to my Windows XP Client Systems. Few systems are getting the IP but most of them are not.
Kindly suggest.
"The IP address lease 192.168.2.101 for the Network Card with network address 002100221539 has been denied by the DHCP server 0.0.0.0 (The DHCP Server sent a DHCPNACK message)."

Renew the client DHCP lease
The IP address for this computer is the same IP address used by another computer on the network. No user action is required. The DHCP client will attempt to get a new IP address from the DHCP server.

To perform these procedures, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

If you do not want to wait for the client to make its automatic renewal attempt, you can manually release and renew the IP address of the client by following these steps:

1.At the DHCP-enabled client computer, click Start, in Start Search type cmd, and then press ENTER.
2.Type ipconfig /release, and then press ENTER.
3.Type ipconfig /renew, and then press ENTER.
Verify
To verify that address conflicts have been resolved:

1.At the DHCP-enabled client computer, click Start, in Start Search type cmd, and then press ENTER.
2.To verify a DHCP client lease, type ipconfig /all to view lease-status information.
3.The output of the ipconfig command should show an IPv4 or IPv6 address marked "preferred."

I am working on a newly build laptop having windows XP. It doesnt assign the DHCP so Release and renew doesnt work on this ..
I am using a software called MacFilterCallOutInstaller.exe to assign DHCP to the allowed machines.
The server is not showing any error but the systems show the mentioned error everytime i try to assign the DHCP.

Please Suggest

did you configure the tool MacFilterCallou...   to accept dhcp request from mac adres: 002100221539?
I don't know about this tool, maybe you can uninstall it and test if this tool is the cause of your problem?

Receiving DHCPNack  means the client believed it had bound an IP address, and when sending a new solicitation to renew, an authoritative DHCP server told the client that the lease it claims to have was invalid.

This is most likely to happen legitimately when plugging in a laptop that was most recently plugged into another network with a different DHCP configuration.

If this is a persistent issue causing outages to clients on your network, then what it suggests is you have multiple DHCP servers in your environment.
Assuming you don't have some type of filtering or restrictions setup on your DHCP server.

One DHCP server configured as authoritative that is sending DHCPNAKs  to clients,
and one  rogue DHCP server  that is not supposed to be authoritative or handing out ips, but is handing out IP addresses anyways.

In the latter case, the solution would be to locate and disable the rogue DHCP server,
and reboot all the client workstations that are malfunctioning
(or issue DHCP release+renew on each one
Start > Run > Cmd
ipconfig /release
ipconfig /renew
)

Most likely candidates for rogue DHCP servers are routers, other servers, or
$50 Wireless Router/Broadband routers mistakenly being used by some network user as a "switch".

You could also verify if this is the case by issuing
"ipconfig /all"
on various computers.


Make sure the DHCP server IP address listed is always the proper
IP address of your authoritative DHCP server;  if it is something else
on any client computer, then you have a rogue.
