Using DHCP reservations and you don’t want to have to use the MMC or remote into the server to make those or see what you have reserved? A quick bit of powershell to make and get those reservations at that exclusive table for you, with a nice little glass of CSV with it!
# A couple of commands to create and get reservations from a remote DHCP server. This requires Powershell Remoting, firewall to open to server, admin rights to server, DhcpServer PS module, and used in ISE 5.1.
# DHCP Remote reservation
$sb = {
$scopeID = "IPsubnet"
$clientMac = "clientmacaddress"
$clientName = "clientcomputername"
$clientIP = "reserveIPaddress"
Add-DhcpServerv4Reservation -ScopeId $scopeID -Name $clientName -IPAddress $clientIP -ClientId $clientMac
}
$dhcpServer = "dhcpservername.fqdn"
Invoke-Command -ComputerName $dhcpServer -ScriptBlock $sb
# Get Remote Reservations
$report =@()
$sb = {
$scopeID = "IPsubnet"
$output = Get-DhcpServerv4Reservation -ScopeId $scopeID | Select-Object Name, IPAddress, ClientID
$report += $output
}
$dhcpServer = "dhcpservername.fqdn"
Invoke-Command -ComputerName $dhcpServer -ScriptBlock $sb
$report | export-csv c:\scripts\logs\dhcpreservations.csv -Append -NoTypeInformation
