I have a numerous set of windows servers. The requirement of Fixed DHCP IP Address may vary for each server. One IT Guy may ask like i need this DHCP Address for 30 days and another may say i need it for 15 days. How can i configure this kind of DHCP lease from the windows 2003 machine to DHCP Server. Is it Possible?

It's a simple matter of changing DHCP Lease duration for the scopes in question. Have a look at the official Microsoft Technet documentation.
If you have varying requirements for different lease lengths on the same subnet, then you have a more unique problem. I'm assuming you are making DHCP reservations for these IP addresses. In that case, it's a simple matter of deleting the reservation and then when the server next reboots or performs a
ipconfig /renewit will be assigned a new IP.Make sure that your pool of reserved IPs is cordoned off with an exclusion mask. You will have to test this for yourself, as I cannot access a test DHCP server at this moment, but it may be possible that reservations can hand out IPs that are in an exclusion range. That would allow you to exclude a range of IPs from normal DHCP leases, and yet still give out those "static DHCP addresses" when a specific MAC address requests an IP.
Having said the above, realize that you are asking DHCP to do something that it was not meant to do and any trouble you run into will be as a result of square pegging a round hole. The better option it so exclude a range of IP space from DHCP leases and then tell people to manually configure an IP address on an interface. When they're done with it, they reconfigure their network interface.
