| Description | Unable to read IO control information from NBT device. |
| Event Information | 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. CAUSE: 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. RESOLUTION: To resolve this problem, obtain the latest service pack for Windows 2000. |
