Skype for Business, formerly Lync 2013, for Windows Phone extends the power of Lync and Skype for.Moving on with this series of deployment articles the next major component of the core Skype for Business (SfB) infrastructure to address is the Edge Server role. Citrix.com 4 Deploying Skype for Business with NetScaler Deployment Guide Front End Servers The front Large PowerPoint files cannot be shared in a meeting. NetScaler’s rich application delivery capabilities significantly enhance the performance of these enterprise applications. Has completed certifications and provided deployment guides for key Microsoft applications including Lync, Exchange, SharePoint and Dynamics CRM.If youre a Skype for Business customer and you need help, please visit Microsoft Office Support. This service may not work correctly, or at.For those following along with these deployment articles to create a lab environment then a simpler companion article entitled Skype for Business 2015 Edge Server Deployment is also available which quickly addresses adding a single Edge Server to this example environment.Skype is great for helping you and your business be more productive. The setting should be On except for blocked domains or On only for allowed domains.Backup and restore your SMS text messages to SD Card or forward the backups via email, MMS, DropBox or Skype. The driving force for selecting that topology was primarily that the much-improved official documentation from Microsoft already covered the deployment of an Enterprise Edition Front End server pool.If you are running Skype for Business Online check that External Access is enabled in Office 365 admin Center ( go to Admin Centers > Teams & Skype > Legacy portal) , choose Organization > External communications. These articles have all focused on a simple Skype for Business topology starting with a single Standard Edition server deployment.The Edge Server article mentioned above is meant for environments built specifically to those articles, while this article basically assumes that there is already at least one Skype for Business Enterprise Edition Front End Pool deployed in the environment. Note that following those articles verbatim only covers the deployment of a single Standard Edition Front End Server, which actually is sufficient to perform this deployment. This means successfully completing the configuration detailed in at least these three articles: Part 1, Part 2, and Part 3. BackgroundA functional Front End server deployment is required before one or more Edge servers can be deployed into the environment. Nearly all of the guidance in this article related to network configuration and server preparation holds true for either scenario. Basically this article is the production deployment reference guide and the other is the lab quick reference guide.
Call Could Not Be Completed Skype For Business Series Of DeploymentThe internally-facing segment contains a dedicated internal private Class A IPv4 addressing scheme that is routed without the use of any Network Address Translation (NAT) to all of the internal servers. In fact these two new servers are not joined to any domain and are simply in the default Workgroup mode.The network configuration used for this environment leverage the best practice model of two separate perimeter networks on different IP address subnetworks. The key difference is that these two servers are located in a Perimeter Network or Demilitarized Zone (DMZ) and thus are not joined to the same Active Directory domain that the rest of the internally-located server roles are. A future article will cover this topic in some capacity.Two virtual servers will be used for this deployment and have already been installed with Windows Server 2012 R2 and prepared using the same methods as the other servers in the environment. To support the myriad of newer clients and platforms the Lyncdiscover service will need to be published using a reverse proxy model of some sort. This role will be addressed after the completion of Edge server deployment, but leveraging some of the legacy behavior that is still supported in even the latest Skype for Business clients will allow for at a minimum of external connectivity from Windows Desktop clients and many IP desk phones. Virus cleaner system macAdditional guidance and various accepted best practice guidance is also intermixed throughout where appropriate. This article by no means is intended to be a single reference on this topic but is meant to show at least one end-to-end deployment scenario by example. The best practice approach of leveraging DNS Load Balancing will also be applied to this Edge pool, there will be no complicated Hardware Load Balancers (HLB) to address.Deploying an Edge Server is a complicated venture as it touches some of the most complex parts and concepts of networking in general. Each Edge Server has three individual public IP addresses assigned directly to a single external interface connected to this network. The Public DMZ is using a full Class C with a natural subnet mask (this is a random network and the individual IP address were just made up for this example). Each server has two network interfaces which are connected to separate networks which cannot route traffic directly between them outside of the dual-homed Edge servers themselves. Network ConfigurationThe following diagram shows a typical network topology for a pair of Edge Servers. The various items required for the actual Edge Server role deployment are identified and outlined but basic Windows Server administration knowledge is assumed. This name can be found in the Network Connections properties or by using the ‘ netsh interface ipv4 show interfaces’ command. To configure all private reserved networks as internally reachable then on each Edge Server run the following netsh commands as an administrator in the Windows Command Prompt or in PowerShell.Netsh interface ipv4 add route 10.0.0.0/8 " Internal" 10.222.4.1Netsh interface ipv4 add route 172.16.0.0/12 " Internal" 10.222.4.1Netsh interface ipv4 add route 192.168.0.0/16 " Internal" 10.222.4.1The ‘ Internal’ string is unique to the server as it is the actual name of the network interface. Either define only the internal networks that exist in the environment below instead of including the entire ranges, or use the configuration below to include all ranges and then add additional static route for the specific external networks and assign the external gateway as the destination for those custom routes. So any connections to hosts on any subnets within these ranges which can only be reached via the external interface can be handled in one of two ways. To allows these servers to find and communicate with internal hosts there is a standard accepted practice of defining static routes for all reserved subnet ranges to utilize the internal interface as the target route.Understand that while IPv4 addresses in these ranges cannot be routed to the Internet there may be cases where some of these subnetworks are actually in use inside the external firewall. This is a good step to perform early as when dealing with public DNS servers it can take several hours for these requests to be created and propagate throughout the Internet.As shown in the diagram each Edge server is assigned 4 unique IP addresses, three on the external network and one on the internal network. DNS ConfigurationWith the prerequisite IP addresses already configured on the Edge servers then the next step is to select Fully Qualified Domain Names (FQDN) to be used in the deployment and then create the required DNS records. The three other entries highlighted above reflect the three static routes used to locate any hosts which might be on the reserved IPv4 address ranges which are not routable over the public Internet.
