OK before all the comments about running XP still, I need help with an issue.I am forced to run a windows XP box to connect to and control some production machines that cost 300K to upgrade and replace, so that's out of the question currently. It has been. Office 365 & Win XP Cloud Computing & SaaS.I just found out what mine was.a Pitney Bowes postage meter. To select directly the 'vendor class identifier' values. TheĬlient implementation of DHCP SHOULD provide a mechanism for the user

Sites may also choose to useĪ DNS name as the 'client identifier', causing address leases to beĪssociated with the DNS name rather than a specific hardware box.ĭHCP clients are free to use any strategy in selecting a DHCP serverĪmong those from which the client receives a DHCPOFFER message.

To use a manufacturer's serial number as the 'client identifier', toĪvoid unexpected changes in a clients network address due to transfer Interface that could be moved to a new client. Results, as that identifier may be associated with a hardware 'chaddr' as the client's unique identifier may cause unexpected It is crucial for a DHCPĬlient to use an identifier unique within the subnet to which theĬlient is attached in the 'client identifier' option. 'client identifier' option, the server MUST use the contents of the Identifier' in all subsequent messages, and the server MUST use that Supplies a 'client identifier', the client MUST use the same 'client The identifier through the 'client identifier' option. The client MAY choose to explicitly provide By the way, this is a /16 network.Ī DHCP server needs to use some unique identifier to associate aĬlient with its lease. I made the reservations using the 12-character MACs because of course, it won't let me do more than that. This is also what their name shows up as (green.) But - if I ping them and check ARP, I see their addresses as normal 12-character MACs. The yellow is "Unique ID"/MAC address as seen by DHCP. So - I do have reservations for these two tablets, but - what happens is, they pull addresses out of the DHCP scope anyway, and when I look at the lease, I see: On my network, what I prefer to do is keep devices such as these in a separate IP range, outside my main scope - using reservations or static addressing (which in this case is not possible.) There is a pair of DCs doing DHCP and DNS. I have no access to the Configuration or OS of these tablets.
On my typical domain (server 2012R2) I have a couple of converted vending machines that were modified (by Grainger) to dispense gloves using a controller that was built on a tablet, which runs Arch Linux.
