Function Get-SpecTVNamingConvention { <# .SYNOPSIS Generates a TeamViewer device alias based on the computer name and Azure table data. .DESCRIPTION The Get-SpecTVNamingConvention function constructs a TeamViewer device alias for a specified computer. It checks the computer name's prefix and either generates an alias without querying Azure tables or retrieves data from specified Azure tables using a Shared Access Signature (SAS) token. The function supports conditional lookups for device and store information from Azure tables based on the computer name. .PARAMETER ComputerName Specifies the computer name. If not provided, the current machine's name will be used by default. .PARAMETER TableSASRO Specifies the read-only SAS token used for accessing the Azure tables. .PARAMETER DeviceIndexTable Specifies the Azure table name containing device index information. .PARAMETER StoreTable Specifies the Azure table name containing store information. .PARAMETER StorageAccount Specifies the Azure storage account name where the tables reside. .EXAMPLE Get-SpecTVNamingConvention -ComputerName "AUC-12345" -TableSASRO "<SAS token>" -DeviceIndexTable "DeviceIndex" -StoreTable "StoreData" -StorageAccount "myStorageAccount" This command generates a TeamViewer alias for the computer "AUC-12345" without querying Azure tables, as the name matches a predefined prefix. .EXAMPLE Get-SpecTVNamingConvention -TableSASRO "<SAS token>" -DeviceIndexTable "DeviceIndex" -StoreTable "StoreData" -StorageAccount "myStorageAccount" This command generates a TeamViewer alias for the current machine, querying the "DeviceIndex" and "StoreData" tables using the provided SAS token. .NOTES Author: owen.heaume Version: 1.0.0 - Initial release 1.0.1 - Now gets all table data for the store table and filters it in the switch statement. (Required for NZR devices) - NZR now has its own logic to generate the alias based off its IP address obtained from the device NIC. 1.0.2 - For NZR devices, now use more accurate local IP address querying - to look for 2 specific subnets. #> [cmdletbinding()] Param ( [string]$ComputerName = $env:COMPUTERNAME, [string]$TableSASRO, [string]$DeviceIndexTable, [string]$StoreTable, [string]$StorageAccount ) Begin { $tableError = $false #If device name starts with... then don't do table calls as they use their hostname as the alias if ($computername -match '^AUC-|^NZC-|^AURR-|^NZRR-|^AUSC-|^NZSC-|^AURT-|^NZRT-|^HKC-|^HKSC-') { Write-Host "No need to make Azure table calls for this host name: $Computername" -ForegroundColor DarkGray } else { if ($DeviceIndexTable -and $computername) { # 1. get Device Index data Write-Host 'Getting table data from: ' -ForegroundColor DarkCyan -NoNewline Write-Host $deviceIndexTable -ForegroundColor DarkGray $params = @{ value = $ComputerName Key = 'HostName' tableName = $DeviceIndexTable StorageAccount = $StorageAccount SASToken = $TableSASRO } try { $deviceData = Get-SpecAzTableRowUsingSAS @params -ea Stop if ($devicedata) { Write-Host 'Got data!' -ForegroundColor DarkGreen } } catch { Write-Error "Table $DeviceIndexTable lookup failed: $_" $tableError = $true } } if (!$tableError) { if ($StoreTable) { # 2. get Store data Write-Host "`nGetting table data from: " -ForegroundColor DarkCyan -NoNewline Write-Host $StoreTable -ForegroundColor DarkGray $params = @{ #value = $deviceData.EPOS #Key = 'RowKey' GetAllRows = $true tableName = $StoreTable StorageAccount = $StorageAccount SASToken = $TableSASRO } try { $storeData = Get-SpecAzTableRowUsingSAS @params -ea Stop Write-Host "Got data!`n" -ForegroundColor DarkGreen } catch { Write-Error "Table $StoreTable lookup failed: $_" $tableError = $true } } } } } Process { if ($tableError) { return $false } # Determine which tables and naming convention are required based on the device's computername switch -Regex ($ComputerName) { '^AUR-|^AUQA-|^NZQA-' { Write-Host 'Computername starts with AUR, NZR, AUQA or NZQA' -ForegroundColor DarkGray # Get the required row using filtering as $storedata contains the entire table $storedata = $storedata | ? { $_.rowkey -eq $devicedata.epos } # 1.
