I am currently running DHCP on a Windows 2008 R2 server, for some reason I keep getting an IP conflict for the same ip address in my DCHP scope and it has tried to assign this address multiple times is there a way to stop DHCP from trying to give this address and what could be causing this.

Thanks

If the address is assigned as a static address on some piece of equipment and it also exists in the DHCP scope, then the DHCP server (which doesn't know that the address is assigned statically) will hand it out to another device. Could this be what is happening?  The way to prevent this is to create a DHCP reservation so that DHCP knows that address is already in use.

You need to adjust your DHCP scope range to exclude the conflicting IP.
Make sure you don't have Firewall also acting as a DHCP Server issuing IP's with an overlapping scope.

Let me know if you need instructions where to change the DHCP scope on your Server 2008.

I found this article from Technet:

http://technet.microsoft.com/en-us/library/ee941125%28v=ws.10%29.aspx

Otherwise the network card of the workstation may have some hardware problem.

From Server Event Viewer any warnings or errors detected ?

My 2 cents
