Hello,
I am trying to retrieve a list of servers on a subnet and then verify if they have a dhcp reservation.
I've found 2 scripts online that do what I need to do, I just need to tie them together.
I'm having trouble exporting the server names gathered from the first script and importing them into the second script. It may be that I can combine them with commands in the middle of the two.
I'd like to export the info found in this script, which is the server names in my domain:
$strCategory = "computer"
$strOperatingSystem = "Windows*Server*"
$objDomain = New-Object System.DirectoryServices.DirectoryEntry
$objSearcher = New-Object System.DirectoryServices.DirectorySearcher
$objSearcher.SearchRoot = $objDomain
$objSearcher.Filter = ("OperatingSystem=$strOperatingSystem")
$colProplist = "name"
foreach ($i in $colPropList){$objSearcher.PropertiesToLoad.Add($i)}
$colResults = $objSearcher.FindAll()
foreach ($objResult in $colResults)
{
$objComputer = $objResult.Properties;
$objComputer.name
}
I'd then like to import the exported information to be included in this script to see if there is a reservation for the servers:
$ComputerName = (Imported names from above)
$NetAdapters = Get-WmiObject Win32_NetworkAdapterConfiguration -ComputerName $ComputerName | ? {$_.DHCPEnabled -eq $True -and $null -ne $_.IPAddress}
If ($NetAdapters) {
Foreach ($Adapter in $NetAdapters) {
foreach ($IP in $Adapter.IPAddress) {
$Reservation = Get-DhcpServerv4Reservation -ScopeId $IP -ComputerName $Adapter.DHCPServer | ? {$_.ScopeId -eq $_.IPAddress}
If ($Reservation) {
Write-Output "$IP is reserved on $($Adapter.DHCPServer)."
} Else {
Write-Output "$IP does not have a reservation."
}
}
}
} Else {
Write-Output "No DHCP Enabled NetAdapters with IPAddresses exist on host, likely Static"
}
Thanks for any assistance.
