DNS registration problem for DHCP XP clients

Hi,

I have problems in local network with DHCP clients, which are not registered in server's DNS. Some details:

SERVER: Win Server 2012
Domain: domain.local
...but due to licensing problem, client computers are NOT joined to domain

Server has DHCP role with settings:
- Enable DNS dynamic updates according to settings below
- Always dynamicaly update DNS A and PTR records
- Dynamically update DNS A and PTR records for clients, that do not request updates
- Under ADVANCED --> CREDENTIALS I have setup a special user, which is member of "DnsUpdateProxy", "DnsAdmins" and "Domain Admins" groups

WEIRD:
Windows 7 clients register properly their IP in DNS! All of them!
...but Windows XP clients do NOT! None of them!

ALL computers have "Printer and Sharing" enabled, and "Network discovery" = ON.
ALL computers are on DHCP retreived IP address.
ALL computers show ports 139 and 445 opened if I scan whole LAN network.

Any idea, what to do to register those old computers in DNS, too?

Hi,

I have tried all that already, but at no avail:
- ipconfig /flushdns
- ipconfig /registerdns
- Network adapter disable/repair
- rebooted several times, bth server and clients
- left it over night and hope it will sort out by itself

All clients have under TCP/IP settings --> Advanced --> Register this connection in DNS enabled

This is your answer

SERVER: Win Server 2012

They need to join the domain in order to register into DNS on the Domain

No, this is not how DNS works.
If you configure SECURITY of DNS and DHCP properly, so that also non-domain users, meaning, non-authenticated users will have a chance to write their own A-record upon DHCP lease, then domain membership is not requirement.

There are clients from old Win 2000 via diferent XP (Home & Pro) thru Vista and Win 7 (Home), so I distanced myself from messing arround with their licencing chaos and left Workgroup environment unchanged.
thanks for trying, but the exact solution I found out myself
