dhcp server EVENT ID1059 & ID1046

    Question

  • Hello,

    problem on server 2008 R2 with DHCP SERVER role. From 1 week, the server does not assign any ip address on the network. In the log, it seems not to be authorized. But when i try to authorize it, it respond "the specified server is already present in the directory service". ID1059 is logged every 1 hour. There is no other dhcp server on the network. I've remove the DHCP ROLE, restart the server and reinstall DHCP ROLE, same problem.

    All informations are appreciated.

    Is the server also domain controller? Did you change some security related settings or add higher security template for the DCs OU?

  • Hi,

    no changed was made in security for the Default Domain Policy and Default Domain Controler Policy. In the DHCP server log, here are the messages :

    I see it's credentials problems but don't know where to search and why this problem appears.
