When you use a Windows 2000-based computer, the following error may be logged in the Application event log after every reboot:
Another symptom is that the NBT Connections counter is not available in System Monitor, although other counters provided by Perfctrs.dll, such as TCP, are available.
Event Type: Error
Event Source: perfctrs
Event Category: None
Event ID: 3101
Description: Unable to read IO control information from NBT device.
This behavior can occur if the Windows 2000 Transmission Control Protocol/Internet Protocol (TCP/IP) performance counters (Perfctrs.dll) are attempting to extract input/output (I/O) control information from a network device, but no network device (network adapter, modem, and so on) is present.
This problem can also occur if the performance counters attempt to extract I/O control information, but the network stack has not completed loading. This is a timing issue and does not necessarily indicate a problem.
To resolve this problem, obtain the latest service pack for Windows 2000. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

NOTE: You can also install the Microsoft Loopback adapter on the computer to try and resolve this behavior.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows 2000 Service Pack 2.
