  • Active Directory Help

    I set up a new server with DNS, DHCP and Active Directory. First question is, is there a problem putting all 3 of these roles on the same server? The server is a Win 2008 R2 server.

    I am having problems adding all of my workstations to the domain. Oddly enough I have only been able to add my workstation to the domain but no others. I have no idea why this is; I've checked the settings on my workstation and they are identical to the other workstations that will not connect to the domain.

    I am running into a wall as far as the next steps to take to find my problem. I am also wondering if this could be a result of reverse or forward look ups.

    I am attaching a screenshot of the error I get when I try and add a workstation to the domain. I am also including the command prompt info from NSLOOKUP and from the servers ipconfig /all.

    NSLOOKUP info:


    > nameservers
    Server: server1.shelter.bhs
    Address: 10.1.10.121

    *** server1.shelter.bhs can't find nameservers: Non-existent domain
    > nslookup
    Server: server1.shelter.bhs
    Address: 10.1.10.121

    *** server1.shelter.bhs can't find nslookup: Non-existent domain
    > set querytype=soa
    > shelter.bhs
    Server: server1.shelter.bhs
    Address: 10.1.10.121

    shelter.bhs
    primary name server = server1.server1
    responsible mail addr = hostmaster.shelter.bhs
    serial = 69
    refresh = 900 (15 mins)
    retry = 600 (10 mins)
    expire = 86400 (1 day)
    default TTL = 3600 (1 hour)

    **seems odd to me that the primary name server says "server1.server1" is this normal?

    Re: Active Directory Help

    It is a DNS problem on the AD/DHCP/DNS server. For some reason it has the primary DNS suffix of Server1 instead of shelter.bhs. Why is another question.

      Re: Active Directory Help

      If this is a new server / AD installation, I would consider blowing it away and starting again
      Did you install DNS before AD or let the DCPROMO Wizard do it? (Preferred option)

      No problem with having DNS/DHCP on a domain controller

        Re: Active Directory Help

        Yes I did install DHCP and DNS before AD and I used the DCPROMO wizard. I'm pretty sure I did try to start the install of AD over but it kept all the settings from the previous install. Is there a way to make it reset for a fresh install of AD.

          Re-run DCPROMO and remove AD
