If your application event log contains the following after every restart:

        Event Type: Error        Event Source: perfctrs        Event Category: None        Event ID: 3101        Date: boot_date        Time: boot_time        User: N/A        Computer: SYSTEM        Description: Unable to read IO control information from NBT device.

Windows 2000 TCP/IP performance counters are trying to get I/O control information from your network device (NIC, modem, ...), but the devices do not exist.

To fix the problem:

1. Run Exctrlst.exe.

2. Select the TCPIP Perfctrs.dll in the list and clear its' Performance Counters Enabled box.

3. Exit the utility and shutdown / Restart your computer.
