    Dear Prajwal,

    Can you please tell me that where is the source file is located??


    • Source files should be located in your Source DVD(.iso) \Sources\sxs.

    Dear Prajwal,

    Sorry for the dumb question. Is the frontend server a separate server or the same server where AD is installed? If it is separate server do we have to install Active directory again in that new server? I am stuck there…..when I install AD in both ( domain controller and FE server) it is giving error while installing Lync and if I do not install AD then it gives me error while preparing active directory from Lync deployment tool…


    • @Venkat – Front server must be a dedicated one. You cannot install Front end server on a domain controller. The server on which you run front end services should not be domain controller nor it should run AD DS.

      • Venkat

        Hello Prajwal,

        Thank you for your swift response. it looks like I am getting confused and going no where. Could you please confirm do I have to install

        1. Prepare Active Directory
        2. Prepare first standard edition server
        3. Prepare Topology

        All the above 3 tasks in AD server and “Install or update Lync server system” in the front end server? My question is how will FE server know the details of AD server as I couldn’t find any setup between those two servers?

        Many thanks in advance.


  • Venkat, you will not install anything on domain controller. You can perform Prepare Active Directory step on either domain controller or on Front end server. The account you are using must be member of domain and schema admins. Perform all steps on front end server, do not do it on DC.

    When you perform Prepare active directory step it inturn extends the Active Directory schema by adding new classes and attributes that are used by Lync Server.

    • Venkat

      Hello Prajwal,

      Thank you. When I try to install to prepare active directory on FE server then the error comes as “Not available: Active Directory permission must be performed on a domain connected machine”

      I am not sure what is that I am missing.

      Please note I am trying to install this on cloud network not our local network. I have taken 2 servers from AWS cloud and wanted to install lync on that. so our office in India and UK can connect to the cloud.


      • Check if the user account permissions once.. You can attach the screenshots in the comment.

        • Venkat

          Sure. The attached screenshot is from FE server. Please let me know if this helps.

          • Venkat

            Also the domain of FE is WORKGROUP and the AD is different. I couldn’t find any documentation on linking these two computers ( as they are two different computers on cloud). If I have to install AD on FE computer then while installing lync it is giving an error as Lync cannot be installed on Domain Controller.


            • venkat – you must first join the FE sever to the domain. It should not be in workgroup. First, bring the FE server in same network as AD is and then join it to the domain. You cannot install AD on FE nor FE on AD.

              • Venkat

                Hello Prajwal,

                Thank you. Yes I am looking on how to join those two computers without installing AD. Could you please send me any documentation references for the same?


                • Venkat

                  Hello Prajwal,

                  Sorry no I am doing this cloud network. Hence it is getting difficult for me join two computers without installing AD.

                  Very sorry to trouble you. Many thanks in advance for your assistance.


                • Venkat

                  Hello Prajwal,

                  Hope you are doing well. I have successfully installed Lync server. When I am trying to connect from Lync client it is asking for Internal and External server name. Do you by any chance know how and where I can get them?

                  Please note I am trying to connect to Lync server from different network.


                • Internal server name is the front end server. Have you configured the Edge server ? Ideally it should not ask for internal server / external server if you are connecting lync client internally.

                • Venkat

                  Hello Prajwal,

                  No I haven’t configured Edge server. When I am trying to connect from local machine which is in our office to Cloud server it says service not available. Then I read few forums that we need to configure internal and external server name.

                  Do we have to have Edge server to connect Lync server which is in different network?


                • Is the client machine able to communicate with front server ? use ping command and check..

                • Venkat

                  Yes when I ping frontend server IP I am getting reply.

                • Provide internal server name as ip/hostname of front end server. Add the same to external server name and try..

                • Venkat

                  I have just tried that and I got this error ” There was a problem verifying the certificate from the server”

                • @Venkat – The client machine does not have the root certificate installed. Export the root cert from the CA (installed on Domain controller) and import it to client machine.

                  You can download the root cert by accessing http://IPAddress of CA/certsrv and download root cert.

                • Venkat

                  I have added the certificate in client machine and when I am trying to sign in it says “We’re having trouble connecting to the server. if this continues, please contact your system administrator”

                • @Venkat – Few things you need to check

                  1) Is the client joined to the domain ?

                  2) Check the DNS server settings on the client and check if its able to resolve the hostnames.

                  3) Have you enabled the lync access for the user from lync control panel. Lync server accepts user names with

                  4) Check whether the lync front end service is started and running on the front end server (check in services.msc). By default the startup mode is Automatic(delayed start), you can change it to Automatic.

                  Hi Prajwal,

                  I think it is failing at step 1.

                  When I am trying domain to add client machine (windows 8) to AD server it says below

                  The following domain controllers were identified by the query:


                  However no domain controllers could be contacted.

                  Common causes of this error include:

                  – Host (A) or (AAAA) records that map the names of the domain controllers to their IP addresses are missing or contain incorrect addresses.

                  – Domain controllers registered in DNS are not connected to the network or are not running.


                • @venkat – Join the client machine to the domain and then try..

                • Venkat

                  Hi Prajwal,

                  Yes while joining the client machine I got the above error.


                • @Venkat – you need to check the connectivity..I am not not sure what environment are you using and how have you configured the machines. You need to fix this from your end.

            • Before you go ahead, go through this once :-

          • Venkat – Two things:-

            a) Is this Front end server a part of domain and is communicating to DC ?

            b) post a screenshot of account permissions that this user account has ?

  • If I am correct this remote tool evaluates the fully qualified domain name (FQDN) that was assigned to the certificate. What is the FQDN mentioned in the cert ?
    See if this link can help you –

  • Did you check if these two machines are able to communicate ?.
    Alternate way – Install the DHCP role on the DC. Power off the VM’s. Open virtual network editor > select the adapter that you have used for VM’s > uncheck the option “Use local DHCP service to distribute IP’s to VM’s”. The second VM should now talk to DHCP to get the IP address.
