DHCP don't do dynamic DNS update for non-Windows DHCP clients since reinstalling DHCP server... RRS feed

  • Question

  • Hi,

    I have a problem that I don't understand. Few days ago I removed my DHCP server was on Windows Server 2003 machine and I reinstalled a new DHCP server on a new Windows Server 2008 R2 machine.

    Everything work fine (not including some machines that I need to reboot or make IPCONFIG /release + IPCONFIG /renew to grab de the DHCP server...). All equipments including PCs, Servers, printers, IP cameras, etc. can renew their IP address without problem. My issue is that all machines that are not a Windows machine (Linux computers, printers, IP cameras, etc.) they are not able to get a DNS entry on my DNS server since this modification. All Windows machines work fine (DNS+DHCP). All non-Windows work only for DHCP.

    I search a solutioon on this problem since 3 days and I don't find the problem. But one thing seem to tell me the problem is coming from the DHCP on Windows Server 2008 R2 and not a access rights problem by the non Windows machines. Why I think that ? Because I have few machine (very new machines) that have a new option was not available on more older equipment where allow Dynamic DNS update directly (not using DHCP). These equipments are with dynamic IP (DHCP) or static IP with the dynamic DNS enabled and I can add their DNS name on my DNS Servers without problem.

    Then I think the problem is coming from my DHCP service is not doing is job correctly. But everything is set properly to do that (In more... all Windows PC in DHCP mode can update theur DNS name also).

    On my DHCP server, in the range options, under DNS tab, all options are checked to enabling DNS update support (Always update DNS dynamically for PTR and A records, Forget PTR and A records when expired and Update dynamically for old machine (NT4.0)).. Translated from my French Windows server ;)

    Bon je vois que mon POST s'est placé dans le forum en français... donc petite traduction rapide:

    Mes clients DHCP non-Windows tel une imprimante, n'est plus capable de mettre à jour son entrée DNS sur mon serveur DNS depuis que mon serveur DHCP a été réinstallé sous Windows Server 2008 R2. Les tests effectués et mon analyse est écrite dans le texte en anglais.

  • Probleme resolu.

    la solution a ete d'ajouter le compte ordinateur dans le groupe AD DnsUpdateProxy. Tres etrangement mes 2 autres serveurs DHCP ne font pas parti de ce groupe et ils fonctionnent bien. 

    la seule difference c'est que la configurarion DHCP de ce serveur a ete importee. ca me fait l'impression que les droits ntfs sur les entrees DNS ont demeurees
