#ValidationTags#Messaging,FlowControl,Pipeline,CodeStyle# function Disable-DbaForceNetworkEncryption { <# .SYNOPSIS Disables Force Encryption for a SQL Server instance .DESCRIPTION Disables Force Encryption for a SQL Server instance. Note that this requires access to the Windows Server, not the SQL instance itself. This setting is found in Configuration Manager. .PARAMETER SqlInstance The target SQL Server instance or instances. Defaults to localhost. .PARAMETER Credential Allows you to login to the computer (not SQL Server instance) using alternative Windows credentials. .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .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. .NOTES Tags: Certificate Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .EXAMPLE PS C:\> Disable-DbaForceNetworkEncryption Disables Force Encryption on the default (MSSQLSERVER) instance on localhost - requires (and checks for) RunAs admin. .EXAMPLE PS C:\> Disable-DbaForceNetworkEncryption -SqlInstance sql01\SQL2008R2SP2 Disables Force Network Encryption for the SQL2008R2SP2 on sql01.
