function Get-DbaClientAlias { <# .SYNOPSIS Gets any SQL Server alias for the specified server(s) .DESCRIPTION Gets SQL Server alias by reading HKLM:\SOFTWARE\Microsoft\MSSQLServer\Client .PARAMETER ComputerName The target computer where the alias has been 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: Server, Management 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 .LINK https://dbatools.io/Get-DbaClientAlias .EXAMPLE PS C:\> Get-DbaClientAlias Gets all SQL Server client aliases on the local computer .EXAMPLE PS C:\> Get-DbaClientAlias -ComputerName workstationx Gets all SQL Server client aliases on Workstationx .EXAMPLE PS C:\> Get-DbaClientAlias -ComputerName workstationx -Credential ad\sqldba Logs into workstationx as ad\sqldba then retrieves all SQL Server client aliases on Workstationx .EXAMPLE PS C:\> 'Server1', 'Server2' | Get-DbaClientAlias Gets all SQL Server client aliases on Server1 and Server2 #> [CmdletBinding()] param ( [Parameter(ValueFromPipeline)] [DbaInstanceParameter[]]$ComputerName = $env:COMPUTERNAME, [PSCredential]$Credential, [switch]$EnableException ) begin { $scriptBlock = { function Get-ItemPropertyValue { param ( [parameter()] [String]$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) { <# DO NOT use Write-Message as this is inside of a scriptblock #> if ((Test-Path $basekey) -eq $false) { continue } $client = "$basekey\Client" if ((Test-Path $client) -eq $false) { continue } $connect = "$client\ConnectTo" if ((Test-Path $connect) -eq $false) { continue } if ($basekey -like "*WOW64*") { $architecture = "32-bit" } else { $architecture = "64-bit" } # "Get SQL Server alias for $ComputerName for $architecture" $all = Get-Item -Path $connect foreach ($entry in $all.Property) { $value = Get-ItemPropertyValue -Path $connect -Name $entry $clean = $value.Replace('DBNMPNTW,', '').Replace('DBMSSOCN,', '') if ($value.StartsWith('DBMSSOCN')) { $protocol = 'TCP/IP' } else { $protocol = 'Named Pipes' } [pscustomobject]@{ ComputerName = $env:COMPUTERNAME NetworkLibrary = $protocol ServerName = $clean AliasName = $entry AliasString = $value Architecture = $architecture } } } } } process { foreach ($computer in $ComputerName) { try { Invoke-Command2 -ComputerName $computer -Credential $Credential -ScriptBlock $scriptBlock -ErrorAction Stop } catch { Stop-Function -Message "Failure" -ErrorRecord $_ -Target $computer -Continue } } } } |
