Ok, i have got a machine that gets its IP from DHCP but
yesterday we had a new phone system installed and the
switch they installed needed to use the same IP address
as the machine i have mentioned above. So i give the
machine a static IP address.

So now everything is ok. I have exclude this IP from
disturbution in Active Directory in the address pool. Now
i want to change the machine back to DHCP instead of
static but for some reason it is still taking the switch
IP even though i have exculded from the address pool in
AD. i think it maybe to do with DNS but not to sure.

Any Ideas?

Cheers

Has this machine been rebooted?
Have you used ipconfig /release to release the IP address lease?
Do you receive the same IP when using ipconfig /release then Ipconfig /renew
Check to see when the lease expires when using the Ipconfig /all command
 
Yeah i did what you said below and it still gives me the
same IP address. How do i sort this problem out i have
checked the lease expire and its the 24th August!

Cheers

Did the IP address change when you set the machine to static?
Is this IP address bound to a NIC that is no longer present?
If you perform a /release /renew does the /all show you a new lease time
(within the past min or 2)
You could always uninstall/reinstall the NIC if you didn't want to
troubleshoot.
