"Host not found in topology" warning

    Question

  • Trying to deploy a Lync Edge server and having some issues.  I set the Edge pool up as a single server in topology builder, exported the config with the Export-csconfiguration command in the Lync shell, installed the local configuration store on the Edge server using that imported zip file, but when I go to setup or remove Lync components, I get this:

     

    Host name: server-w908
    WARNING! Host not found in topology. All roles will be uninstalled.

     

    I don't get it.  In another thread, the following troubleshooting steps were offered:

     

    - Make sure the Edge computer is NOT part of the domain -- (it is not on the domain)
    - Make sure the computer has the computer name "server-w908" -- (<--edited for my server name.  What's interesting is that in my scenario, the server name is coming up without the FQDN, even though I have the FQDN set in the topology builder)
    - Make sure the DNS Suffix is correct (advanced settings) -- (the DNS suffix isn't even showing up in the error...but I have the DNS suffix set on both the internal and external NIC)
    - Make sure the Edge server has the Interfaces configured as you entered them in topology builder. (I have the correct IP addresses for both NICs in topology builder)

    Suggestions much appreciated.

  • Hi Philip,

     

    The "Hostname" you see, is what the installation finds when it query the server. Since the hostname on the server does not match the FQDN entered in the topologybuilder, it will fail.

    Try changing the hostname from serverXXX to serverXXX.domain.com (Suffixes on network adapters does not apply here) as described here: http://technet.microsoft.com/en-us/library/gg398591.aspx

  • Go to the System properties of the server, where you set the name of the computer. Click the button labeled "Change" as if you were going to change the name. Then click the "More" button and type the DNS suffix here. This configured the FQDN for non-domain joined computers.

  • Hi,Philip,

    Like as Lasse mentioned,the error caused by that your server name isn't matched to the FQDN you defined in topology.You need add the DNS suffix for your edge server following Jamie's steps and create a DNS A record in your DNS server.

    You also can refer the following documents to configure DNS record and DNS suffix for your Edge Server

    Configure DNS suffix http://technet.microsoft.com/en-us/library/gg398488.aspx

    Configure DNS record http://technet.microsoft.com/en-us/library/gg398288.aspx

  • I'm not sure what you mean.  What am I changing if not the DNS suffix on the network adapters?  I cannot find any reference to host names in that linked article.
