Question : Problem: Windows XP won't hold a static IP address for either of two NICs

I have a work station that has two network cards (one built in and one added on), each configured with a static IP address talking to two different networks.  I was experiencing some network trouble with one of the connections (the add on card), so I put in a new network card, and removed the old one.

Now when I try to assign either of my two network cards a static IP address the information doesn't stay.  After I click OK, and then go back in to look at it - it is set back to DHCP.  I have tried re-installing the network drivers, but the issue remains.  even though the settings appear blank it seems to keep the static IP until I reboot, or after some type of timeout period, then goes back to DHCP, and tries to get an address.  I have tried disabling each of the cards and configuring the other - didn't work.  I have removed the add-on card and tried configuring the on-board card alone - didn't work.

The workstation is a Dell Precision 370, with XP SP2 and all current updates.
The built-in NIC is a Broadcom 57xx Gigabit
the add-on is a SysKonnect SK-9E21d Gigabit PCI-Express

The previous add-on card was an Intel VE/100 PCI card

Answer : Problem: Windows XP won't hold a static IP address for either of two NICs

I'm going to re-format the computer to fix this error.
