Purpose: This script will search AD for Window computers and attempted to connect to each one. Then it will read the contents of the host file and write them to a csv file.
Note: This will take a while to run unless someone wants to make it multithreaded.
I just wrote this so there may need to be some bug fixes but in general it seemed to work.
#Read all host files and write to CSV file Import-Module ActiveDirectory $PATH = "c:\temp\hostfiles.csv" $myCol = @() $AllComputers = Get-ADComputer -Filter {OperatingSystem -Like "Windows*"} -Property * | Select -Expand Name foreach ($Computer in $AllComputers){ $i++ Write-Progress -activity "Scanning Machine $Computer " -status "Scanned: $i of $($AllComputers.Count)" -percentComplete (($i / $AllComputers.Count) * 100) Get-Content -Path "\\$Computer\c$\windows\system32\drivers\etc\hosts" | where {!$_.StartsWith("#")} | foreach { if ($_ -ne ""){ $data = $_ -split " ",2 $Hosts = New-Object -TypeName PSObject -Property @{ Host = $Computer IPAddress = $data[0].Trim() Node = $data[1].Trim() } } $myCol += $Hosts } $myCol |Select Host,Node,IPAddress| Export-Csv -Path $PATH -NoTypeInformation }
