#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 - defaults to localhost. .PARAMETER Credential Allows you to login to the computer (not sql instance) using alternative Windows credentials .PARAMETER Silent Use this switch to disable any kind of verbose messages .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 .EXAMPLE Disable-DbaForceNetworkEncryption Disables Force Encryption on the default (MSSQLSERVER) instance on localhost - requires (and checks for) RunAs admin. .EXAMPLE Disable-DbaForceNetworkEncryption -SqlInstance sql01\SQL2008R2SP2 Disables Force Network Encryption for the SQL2008R2SP2 on sql01. Uses Windows Credentials to both login and modify the registry. .EXAMPLE Disable-DbaForceNetworkEncryption -SqlInstance sql01\SQL2008R2SP2 -WhatIf Shows what would happen if the command were executed. .NOTES Tags: Certificate Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 #> [CmdletBinding(SupportsShouldProcess, ConfirmImpact = "Low")] param ( [Parameter(ValueFromPipeline = $true)] [Alias("ServerInstance", "SqlServer", "ComputerName")] [DbaInstanceParameter[]] $SqlInstance = $env:COMPUTERNAME, [PSCredential] $Credential, [switch] $Silent ) process { foreach ($instance in $sqlinstance) { Write-Message -Level VeryVerbose -Message "Processing $instance" -Target $instance $null = Test-ElevationRequirement -ComputerName $instance -Continue Write-Message -Level Verbose -Message "Resolving hostname" $resolved = $null $resolved = Resolve-DbaNetworkName -ComputerName $instance -Turbo if ($null -eq $resolved) { Stop-Function -Message "Can't resolve $instance" -Target $instance -Continue -Category InvalidArgument } Write-Message -Level Output -Message "Connecting to SQL WMI on $($instance.ComputerName)" try { $sqlwmi = Invoke-ManagedComputerCommand -ComputerName $resolved.FQDN -ScriptBlock { $wmi.Services } -Credential $Credential -ErrorAction Stop | Where-Object DisplayName -eq "SQL Server ($($instance.InstanceName))" } catch { Stop-Function -Message "Failed to access $instance" -Target $instance -Continue -ErrorRecord $_ } $regroot = ($sqlwmi.AdvancedProperties | Where-Object Name -eq REGROOT).Value $vsname = ($sqlwmi.AdvancedProperties | Where-Object Name -eq VSNAME).Value $instancename = $sqlwmi.DisplayName.Replace('SQL Server (', '').Replace(')', '') # Don't clown, I don't know regex :( $serviceaccount = $sqlwmi.ServiceAccount if ([System.String]::IsNullOrEmpty($regroot)) { $regroot = $sqlwmi.AdvancedProperties | Where-Object { $_ -match 'REGROOT' } $vsname = $sqlwmi.AdvancedProperties | Where-Object { $_ -match 'VSNAME' } if (![System.String]::IsNullOrEmpty($regroot)) { $regroot = ($regroot -Split 'Value\=')[1] $vsname = ($vsname -Split 'Value\=')[1] } else { Stop-Function -Message "Can't find instance $vsname on $instance" -Continue -Category ObjectNotFound -Target $instance } } if ([System.String]::IsNullOrEmpty($vsname)) { $vsname = $instance } Write-Message -Level Output -Message "Regroot: $regroot" -Target $instance Write-Message -Level Output -Message "ServiceAcct: $serviceaccount" -Target $instance Write-Message -Level Output -Message "InstanceName: $instancename" -Target $instance Write-Message -Level Output -Message "VSNAME: $vsname" -Target $instance $scriptblock = { $regpath = "Registry::HKEY_LOCAL_MACHINE\$($args[0])\MSSQLServer\SuperSocketNetLib" $cert = (Get-ItemProperty -Path $regpath -Name Certificate).Certificate $oldvalue = (Get-ItemProperty -Path $regpath -Name ForceEncryption).ForceEncryption Set-ItemProperty -Path $regpath -Name ForceEncryption -Value $false $forceencryption = (Get-ItemProperty -Path $regpath -Name ForceEncryption).ForceEncryption [pscustomobject]@{ ComputerName = $env:COMPUTERNAME InstanceName = $args[2] SqlInstance = $args[1] ForceEncryption = ($forceencryption -eq $true) CertificateThumbprint = $cert } } if ($PScmdlet.ShouldProcess("local", "Connecting to $instance to modify the ForceEncryption value in $regroot for $($instance.InstanceName)")) { try { Invoke-Command2 -ComputerName $resolved.fqdn -Credential $Credential -ArgumentList $regroot, $vsname, $instancename -ScriptBlock $scriptblock -ErrorAction Stop Write-Message -Level Critical -Message "Force encryption was successfully set on $($resolved.fqdn) for the $instancename instance.
