#Simple Server list $servers = Get-Content C:\servers.txt # Loop through all servers and check key foreach ($server in $servers) { $REG = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey('LocalMachine', $server) $REGKEY = $REG.OpenSubKey("SYSTEM\CurrentControlSet\Control\Lsa") $val = $REGKEY.GetValue("DisableLoopBackCheck") # If the key is missing or not set it will be displayed in red # If the key is set it will be displayed in green if (!$val){ Write-Host $server "is not set" -ForegroundColor Red } if ($val -ne "1"){ Write-Host $server "is not set properly" -ForegroundColor Red } else{ Write-Host $server "is set" -ForegroundColor Green } } |
What the Script Does
In the sample above it will check the “DisableLoopBackCheck” key across a list of servers and if the key does not exist or not set to “1” it will be reported in the output.
Example:
You can simply change which key to check and the desired value to make this work for your scenario.
I hope this helps make your job easier in the future.
