Bug Check 0xBC: NETWORK_BOOT_DUPLICATE_ADDRESS

The NETWORK_BOOT_DUPLICATE_ADDRESS bug check has a value of 0x000000BC. This indicates that a duplicate IP address was assigned to this machine while booting off a network.

Important Info If You Have Received a STOP Code

bsod

If you received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss.

For information about how to recover from this error, see Resolving Blue Screen errors in Windows.

NETWORK_BOOT_DUPLICATE_ADDRESS Parameters

The following parameters are displayed on the blue screen.

ParameterDescription

1

The IP address, shown as a DWORD. An address of the form aa.bb.cc.dd will appear as 0xDDCCBBAA.

2

The hardware address of the other machine. (For an Ethernet connection, see the following note.)

3

The hardware address of the other machine. (For an Ethernet connection, see the following note.)

4

The hardware address of the other machine. (For an Ethernet connection, this will be zero.)

 

Note   When Parameter 4 equals zero, this indicates an Ethernet connection. In that case, the MAC address will be stored in Parameter 2 and Parameter 3. An Ethernet MAC address of the form aa-bb-cc-dd-ee-ff will cause Parameter 2 to equal 0xAABBCCDD, and Parameter 3 to equal 0xEEFF0000.

Cause

This error indicates that when TCP/IP sent out an ARP for its IP address, it got a response from another machine indicating a duplicate IP address.

When Windows is booting off a network, this is a fatal error.
