Ran across this one after a network card replacement. When trying to assign a static address to the replacement, I kept getting warning messages that the IP address was already assigned to an adapter in the system. A little bit of research showed the simple fix. The full error message you'd receive is:
The IP address XXX.XXX.XXX.XXX you have entered for this network adapter is already assigned to another adapter Name of adapter . Name of adapter is hidden from the network and Dial-up Connections folder because it is not physically in the computer or is a legacy adapter that is not working. If the same address is assigned to both adapters and they become active, only one of them will use this address. This may result in incorrect system configuration. Do you want to enter a different IP address for this adapter in the list of IP addresses in the advanced dialog box?
The fix is easy.
To resolve this problem, uninstall the ghosted network adapter from the registry:
Click Start , click Run , type cmd.exe , and then press ENTER.
Type set devmgr_show_nonpresent_devices=1 , and then press ENTER.
Type Start DEVMGMT.MSC , and then press ENTER.
Click View , and then click Show Hidden Devices .
Expand the Network Adapters tree.
Right-click the dimmed network adapter, and then click Uninstall .
Now close the device manager and you're done.
