Hi,

You can use command Set- Dhcp Serverv4Option Value to change the option.

**Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -OptionId 12 -Value "hostname" **

Please refer to the link below:

I get an error

Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ScopeId 10.10.10.0 -OptionId 12 -Value "hostname"

"computerName" is the name of the reservation of my computer?

I have reservations in which I would like to enter the HOSTNAME for all my reservations, obviously they all have different names.

PS C:\Windows\system32> Set-DhcpServerv4OptionValue -ComputerName "DELL_3040.upn.parisnanterre.fr" -ScopeId 172.28.0.0 -OptionId 12 -Value "PIPO"

Hi,

"computerName" is your DNS server name.

Set option value for DNS server for a reservation:

Set-DhcpServerv4OptionValue -ComputerName "dhcpserver.contoso.com" -ReservedIP 10.10.10.5 -OptionId 12 -Value "hostname"

Best regards,
