Important Info If You Have Received a STOP Code
If you received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error. If your copy of Windows came with your computer, call the manufacturer of your computer. If you purchased Windows separately from your computer, Microsoft provides support. To find contact info for Microsoft or your computer manufacturer, Contact Support.
If you have experience with computers and want to try to recover from this error, follow the steps provided in the Microsoft article Resolving STOP (Blue Screen) Errors in Windows.
These actions might prevent an error like this from happening again:
- Download and install updates and device drivers for your computer from Windows Update.
- Scan your computer for computer viruses.
- Check your hard disk for errors.
NETWORK_BOOT_DUPLICATE_ADDRESS Parameters
The following parameters are displayed on the blue screen.
| Parameter | Description |
|---|---|
|
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.
