Federation service failed to find a Domain controller RRS feed

  • Question

  • Hi,

    We are getting this below error on ADFS 2012r2 environment,

    The Federation Service failed to find a domain controller for the domain NT AUTHORITY. 

    Additional Data 
    Domain Name: NT AUTHORITY 
    Error: 1212 

    User Action 
    Use Nltest to determine why DC locator is failing. Nltest is part of the Windows Support Tools.

    we have tried following steps, 

    NLTEST , got the Domain Details

    Port Opening are fine

    Not all the RPT have issues, only authendication failing for few users

    Re-Joined the ADFS server successfully

    Nslookup to the DC works fine

    On DCs, DCDIAG is fine.

    is there anything else, we could try to solve the issue? and how federation connects to AD? 

    Please give your suggestions., Thanks in advance

    Thanks and Regards
