Enabling TCP/IP on multiple interfaces using PowerShell (part of hands free SQL Server installation)

  • Article

In trying to install SQL Server completely "hands free" I struck a snag  - by default the TCP/IP protocol is installed, but the interfaces are all "Enabled=false", which would require a manual step to enable them.

Naturally - PowerShell to the rescue!

To view the basic post-install state, open up the SQL Server Configuration Manager (below)

 

Double-click TCP/IP and switch to the "IP Addresses" tab.  Ah ha!  The culprit - "enabled" is set to "No" on each interface (IP1, IP2, etc)

 

After some basic searching I found the following Technet article - however it enables TCP "in general", but not specifically for each interface.  After further searching - I didn't find a suitable script to fix the problem, so I was forced to research and build one (see below).

 

The following script sets "Enabled" and the "Port" for each IP address.  Note the odd structure of ipaddressproperties field underneath a given ipaddress.

Enjoy!

 

As always - comments / fixes are welcomed!
