Error Message When You Try
to Set an IP Address on a Network Adapter
When you trying to set the IP address on a
network adapter, you may receive the following error message:
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?
Where XXX.XXX.XXX.XXX is the IP
address that you are trying to set and Name of adapter is the name of
the network adapter that is present in the registry but hidden in Device
Manager.
If you click Yes, you see the TCP/IP properties where you can change the
IP address to something different for the currently showing network adapter in
Device Manager. If you click No, the IP address is assigned to the
network adapter. Note that if you click No, the selected network adapter
in Device Manager and the ghosted network adapter have the same IP address. In
most cases, this does not cause any problems because the driver is disabled.
A network adapter with the same IP address is in
the registry but is hidden in Device Manager. This can occur when you move a
network card from one PCI slot to another PCI slot.
To resolve this problem,
uninstall the ghosted network adapter from the registry:
