DNS entry keeps getting the old DHCP lease info

I have a DNS entry that keeps coming back and I don't know where from.  We had a server get a new motherboard put in and it picked up a dhcp address.  We changed it back to a static address, but the dhcp address keeps popping back into the DNS.  Any ideas?  I've checked the only connection on the server and it is static with the right address.

Nope, both dhcp servers are not showing this IP assigned to anything.

Was this box ever on dhcp or has it ALWAYS been statically assigned?
Did you remove the old NIC drivers etc from the system before/after the MB was changed?
What type of DNS entry is being added, is it just the host record for this server?
Any hosts filesactive and located on any of your servers?
All wins entries and dns cache cleared?

Running ipconfig /all on the server, does it show as dhcp or not in the autonegotiated field?
If you correct the entry, when does it go wrong again, after the next reboot?

This box was on dhcp right after teh mobo was changed.  We then switched it back to static.  We did not remove the nic drivers.  I did go in and show the hidden/removed items and uninstalled the two nics that were in there.
It is just a host record that continues to appear in DNS.  I haven't tried assigning it to another computer although I can do that.
There are no hosts files that would point to this dhcp address.
We cleared all the dns cache on all known machines that connect to this system.
The dhcp is showing up almost daily.  I remove it in the morning and it is back the next day.  The system has not rebooted in weeks.

Hope that helps.

Is the NIC that is being registered in DNS set to register automatically?
This is only a temporary thing to see what is happening. Open the NIC properties and select the tcpip settings.
in advanced, select DNS. Is the box at the bottom ticked or not ticked for registering? Either add or remove the tick.

I would seriously consider rebooting the box. If that something has not cleared down properly from the change this it could be just that simple.

Ok, I took off the check box for register dns connections.  We'll leave it over the weekend and if nothing give it a reboot on Monday.

Got back and the entry is back in DNS so I did a reboot.  We'll see tomorrow if it shows up again.
