Function Get-DbaClientAlias { <# .SYNOPSIS Creates/updates a sql alias for the specified server - mimics cliconfg.exe .DESCRIPTION Creates/updates a SQL Server alias by altering HKLM:\SOFTWARE\Microsoft\MSSQLServer\Client .PARAMETER ComputerName The target computer where the alias will be created .PARAMETER Credential Allows you to login to remote computers using alternative credentials .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: Alias Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Get-DbaClientAlias .EXAMPLE Get-DbaClientAlias Gets all SQL Server client aliases on the local computer .EXAMPLE Get-DbaClientAlias -ComputerName workstationx Gets all SQL Server client aliases on Workstationx #> [CmdletBinding()] Param ( [DbaInstanceParameter[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [switch][Alias('Silent')]$EnableException ) process { foreach ($computer in $ComputerName) { $scriptblock = { function Get-ItemPropertyValue { Param ( [parameter()] [String]$Path, [parameter()] [String]$Name ) (Get-ItemProperty -LiteralPath $Path -Name $Name).$Name } $basekeys = "HKLM:\SOFTWARE\WOW6432Node\Microsoft\MSSQLServer", "HKLM:\SOFTWARE\Microsoft\MSSQLServer" foreach ($basekey in $basekeys) { if ((Test-Path $basekey) -eq $false) { Write-Warning "Base key ($basekey) does not exist.
