I have one computer that is getting the wrong DHCP IP.  It also had the wrong DNS, which I fixed by changing the nic settings to a manual IP.  
How do I fix the DHCP IP

First of all do ipconfig /all on the affected computer, find out which server is supplying the IP address as you may have more than 1 DHCP server

If however you only have 1 DHCP server, make sure there are no active reservations for that particular NIC card.

Another option is to rigt click on the network icon in the system tray area and select "Troubleshoot problems" It may resolve the problem as well.

It is getting it's DHCP address from the wireless router.  Not sure why.  The other 4 computers are getting theirs from the DHCP server.  
Gotta go to a dinne.  I'll check back tomorrow.

Most likely the  wireless router is also configured as a DHCP server.
Disabling this should take care of the problem.

yep there were two DHCP's giving out IP's.  I disabled the wireless.  Both answers were correct.

Thanks
