JSI Tip 9453. When you upgrade Windows 2000 Server with Service Pack 4 to Windows Server 2003 integrated with Service Pack 1 an Event ID 4311 error is recorded in the System event log?

When you upgrade from Window 2000 Server with SP4 to Windows Server 2003 integrated with SP1, the System event log records:

Event Source: NetBT
Event Category: None
Event ID: 4311
Time: HH:MM:SS
Type: Error
User: N/A Computer: <Computer Name>
Description: Initialization failed because the driver device could not be created.

Windows redetects the network adapter during the upgrade, and erroneously posts an error condition. The adapter functions normally.

You may safely ignore this error.
