Changing a network adapter's MAC address
The MAC address individually owned by a network adapter will change when a
LAN card, motherboard or LAN mezzanine is replaced.
In the following cases, the work for recognizing a new MAC address is required:
• If the peripheral equipment of a destination provides fixed MAC address
management:
To update the MAC address of the peripherals, restart the peripherals after
replacing the motherboard or LAN component and turn on the system unit.
• If a user program or an application program manages a MAC address:
If a user program or an application specifies management of MAC address
values, update data to a new MAC address after replacing the motherboard or
LAN component.
• If you use LAN extended functions:
The LAN extended functions share one MAC address with two network
adapters which are primary card and secondary card.
Delete the setting of LAN extended functions before replacing the
motherboard or LAN component. After replacing a component, set again the
LAN extended functions.
For details on how to use the LAN utility, see Windows Server 2008 R2 LAN
Extended Functions User's Guide.
