The information in this article applies to:

  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1
  • Microsoft Windows NT Workstation versions 3.5 and 3.51
  • Microsoft Windows NT Server versions 3.5 and 3.51

SYMPTOMS

After you upgrade to Windows NT version 3.5 or 3.51 and you try to install TCP/IP protocol and related components, TCP/IP Internetworking components are unavailable (dimmed) and the file size states 0 kilobytes (K). The option to Enable Automatic DHCP Configuration is also unavailable.

CAUSE

This problem occurs if TCP/IP protocol was previously installed and incorrectly removed.

RESOLUTION

To correct this problem, you may need to modify the Registry.

WARNING: Using Registry Editor incorrectly can cause serious, system-wide problems that may require you to reinstall Windows NT to correct them. Microsoft cannot guarantee that any problems resulting from the use of Registry Editor can be solved. Use this tool at your own risk.

  1. Start Registry Editor and go to the following subkey: 

          HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services

  2. Remove the Tcpip key and its subkeys. Also remove the TcpipCU key and its subkeys if it exists.

  3. Go to the following subkey: 

          HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft

  4. Remove the Tcpip key and its subkeys. Also remove the TcpipCU key and its subkeys if it exists.

  5. Exit Registry Editor and restart Windows NT.
