function Set-DbaTcpPort { <# .SYNOPSIS Changes the TCP port used by the specified SQL Server. .DESCRIPTION This function changes the TCP port used by the specified SQL Server. Be aware that the Database Engine begins listening on a new port only when restarted. So you have to restart the Database Engine that the new settings become effective. .PARAMETER SqlInstance The target SQL Server instance or instances. .PARAMETER SqlCredential Credential object used to connect to the SQL Server instance as a different user. .PARAMETER Credential Credential object used to connect to the Windows server itself as a different user (like SQL Configuration Manager). .PARAMETER Port TCPPort that SQLService should listen on. .PARAMETER IpAddress Ip address to which the change should apply, if omitted allip (0.0.0.0) will be changed with the new port number. .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .PARAMETER WhatIf Shows what would happen if the command were to run. No actions are actually performed. .PARAMETER Confirm Prompts you for confirmation before executing any changing operations within the command. .NOTES Tags: Service, Port, TCP, Configure Author: @H0s0n77 Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Set-DbaTcpPort .EXAMPLE PS C:\> Set-DbaTcpPort -SqlInstance sql2017 -Port 1433 Sets the port number 1433 for all IP Addresses on the default instance on sql2017.
