Cannot Install TCP/IP After Installing SQL Server (128430)


The information in this article applies to:

  • Microsoft Windows NT Workstation 3.5
  • Microsoft Windows NT Server 3.5
This article was previously published under Q128430

SYMPTOMS

After you install SQL server and then run Control Panel to install TCP/IP, Connectivity Utilities is unavailable (grayed out), even though TCP/IP is not installed.

CAUSE

When you install SQL Server and choose to include the TCP/IP connectivity on a computer running Windows NT without TCP/IP installed, a message is displayed that asks you if you want to proceed. If you select Yes, false TCP/IP and Parameter keys are created in the following registry key under the HKEY_LOCAL_MACHINE subtree: 

   \SYSTEM\CURRENTCONTROLSET\SERVICES


When you attempt to install TCP/IP, Windows NT finds the registry entries, and believes that TCP/IP is already installed, and installs utilities, but not the protocol.

WORKAROUND

To work around this problem, delete the registry keys created by SQL Server, install TCP/IP, and then reinstall SQL Server.
