A. This problem can occur if you use Checkpoint Firewall or VPN software and you delete the registry key for a NIC or make substantial changes to the network on a Windows NT 4.0 server/workstation. To resolve the problem, perform the following steps:

  1. Remove CheckPoint Firewall or your VPN software.

  2. Copy tcpip.sys from the latest service pack to %systemroot%system32.

  3. If the tcpip.sys file is compressed (tcpip.sy_), use the following command to extract it:

    expand c:winntsystem32tcpip.sy_ c:winntsystem32

  4. Reboot the PC.

  5. Reinstall CheckPoint Firewall or your VPN software.
