Tutorial: 802.1X Authentication via WiFi – Active Directory + Network Policy Server + Cisco WLAN + Group Policy

Here is how to implement 802.1X authentication in a Windows Server 2008 R2 domain environment using Protected-EAP authentication.  I have designed the tutorial to be worked on in the specific order to prevent downtime if deployed during the day.  By creating the Network Policy server first, once we switch the authentication type from whatever to 802.1X via RADIUS, our Network Policy Server will immediately start processing requests and allowing machines on the domain.  By configuring the Cisco Wireless LAN Controller or Group Policy first, clients will try connecting to a RADIUS server that doesn’t exist or present invalid credentials.  If you have any suggestions on how to better the implementation I demonstrate here, please drop a comment below to improve security/stability of these types of deployments. 🙂

Active Directory

First, we need to create a security group in Active Directory to allow a list of specific users and computers to login to the domain.  In this example, we will allow any authenticated user or machine on the domain to authenticate successfully to the RADIUS sever.  In the screenshot below, we can see I have added both Domain Users and Domain Computers to a security group called WirelessAccess. Here is a screenshot with the above settings.

Network Policy Server

  1. Create a new Windows Server 2008 R2 or Windows Server 2012 machine
  2. Add the machine to the domain
  3. Give the machine a static IP: (I’ll use 10.10.10.15 throughout this document as a reference to this server)
  4. Open up Server Manager, click Add Roles, click Next on the Before You Begin screen, check Network Policy and Access Services and click Next, click Next on the Introduction screen, check Network Policy Server (leave the rest unchecked) and click Next, click Install.
  5. Once Network Policy Server is installed, launch the Network Policy Server snap-in (via MMC or Administrative Tools)
  6. Inside of Network Policy Server, on NPC (Local), select RADIUS server for 802.1X Wireless or Wired Connections from the dropdown and click Configure 802.1X
    1. On the Select 802.1X Connections Type page, select Secure Wireless Connections, and enter My Company’s Wireless.  Click Next.
    2. Click on the Add… button.  Enter the following settings:
      1. Friendly name: Cisco WLAN Controller
      2. Address: 10.10.10.10 (Enter your WLAN Controller’s IP address)
      3. Select Generate, click the Genereate button, and then copy down the Shared Secret the wizard generated (we will use this later to get the WLAN Controller to talk to the RADIUS server).  Click OK.
    3. Click Next.
    4. On the Configure an Authentication Method, select Microsoft: Protected EAP (PEAP). Click Next.
    5. Click Next on the Specify User Groups (we will come back to this).
    6. Click Next on the Configure Traffic Controls page.
    7. Click Finish
  7. Click on NPS (Local) -> Policies -> Network Policies. Right click Secure Wireless Connections and click Properties.
  8. Click on the Conditions tab, select NAS Port Type, and click Remove.
  9. Still on the Conditions tab, click Add…, select Windows Groups and click Add…, click Add Groups…, search for WirelessAccess and click OK.  Click OK on the Windows Groups dialog box, click Apply on the Secure Wireless Connections Properties box.  You should now have something like the image below:

Creating an installer for your application in Visual Studio 2012

In Visual Studio 2012, Microsoft removed the ability to make quick installers for your application. Now they recommend using a third party like Wix or InstallShield. This tutorial will go over using InstallSheild’s free light version to make an installer for your application.

Please note, you cannot use InstallShield’s product with the Express versions of Visual Studio.  If you use the express edition, you will not see the “Other Project Types” and “Setup and Deployment” folders mentioned later on.

First head over to InstallShield’s website and register for the product.  It is free, but you have to register with a valid email address to receive a license key:

http://learn.flexerasoftware.com/content/IS-EVAL-InstallShield-Limited-Edition-Visual-Studio?lang=1033&ver=pro

Download and install the program.

Once installation is done, launch the program below as an Administrator:

C:\Program Files (x86)\InstallShield\2012SpringLE\System\TSConfig.exe

Enter your serial number from an auto-generated email they sent you when you downloaded InstallShield Limited and hit Activate.

InstallShield License

Next, open up Visual Studio 2012 (again, note we are not using express)

Click File->New Project.

New Project - Visual Studio

Expand Other Project Types and select Setup and Deployment.  Inside of there, you should see InstallShield Limited Edition Project (again, you won’t see this in Visual Studio Express editions).  Click OK.

Other Project Types - InstallShield

At this point, you should see a guided GUI (Project Assistant) to create your installer.  Inside of the Solution Explorer, you will see additional items you can select to configure advanced options.

Lync 2010 – Deploying Monitoring Server Reports

I recently had the lovely experience of setting up the monitoring role for Lync 2010.  In doing so, I documented the steps I took to successfully deploy the Monitoring Server Reports Services.

Before beginning, here are a few notes:

  • Ensure you are using Microsoft SQL Server 2008 x64 Standard or greater (if you need to upgrade, see the following tutorial: SQL Server 2008 R2 – Updating a msSQL instance/server)
  • You have deployed Lync 2010 Standard or Enterprise
    • Both versions allow you to add this service

Alright, so lets begin!

  1. Our first step is to install the “Reporting Services” feature for SQL Server 2008
  2. Open up the Reporting Services Configuration Manager
  3. Enter the SQL Server Reporrting Services instance you want to connect to
  4. Click Web Service URL
  5. Enter the virtual directory name, port, and configure your SSL certificate
  6. Click Apply
    1. Note: If you had IIS on this box, you will need to choose different port numbers
  7. Open up Microsoft SQL Server Management Studio
  8. Login to your SQL server and create a new service account for your SQL server
    1. Make a sysadmin for the time being
  9. Head back over to the Reporting Services Configuration Manager
  10. Setup the Database Name and select the language.
  11. Leave Native Mode selected and click Next.
  12. Enter the same credentials on the Credentials step and click Next
  13. Click Next on the Summary pane
  14. Click Finish
  15. Go back to your SQL Server and deprivilege your account
    1. Uncheck sysadmin and Set the default database to ReportServer
  16. Click on the Report manager URL in the reporting Services Configuration Manager
  17. Click Reports if you are happy with the /Reports directory
  18. Once you have clicked Apply, verify you can view the website by clicking on the link it shows (it should bring you to a site that kind of reminds you of an old version of sharepoint :P)
  19. Go to your Lync Front End server and run the Lync Server Topology Builder program (Start->All Programs->Microsoft Lync Server 2010->Lync Server Topology Builder)
  20. Upon login, check “Download Topology from existing deployment” and click OK
  21. Save the topology to your desktop when prompted (or anywhere else, doesn’t really matter)
  22. Expand your Site, and click on the Monitoring Servers folder
  23. Right click on Monitoring Servers and select New Monitoring Server…
  24. Enter in the server to install the role on
  25. Enter the SQL server name/instance to use
  26. Finish the installation
  27. Head over to the server where you are going to install the Monitoring/Archieving role
  28. Open up the Lync Server 2010 – Deployment Wizard (run as administrator)
  29. Click on Install or Update Lync Server System
  30. Click on Setup or Remove Lync Server Componenets
  31. Let it install/configure all of its stuff
  32. Click on Run next to Server Status (Optional)
  33. Verify Lync Server Call Detail Recording and Lync Server QoE Monitoring Service services have been started (start them if they aren’t running)
  34. Go back to the Lync Server 2010 deployment wizard homepage and click on Deploy Monitoring Server Reports
  35. The server information should already be prefilled in. Click Next
  36. Enter in the SQL credentials needed to connect in
    1. For this step, I would recommend creating the account yourself (A good tutorial I came across on doing this can be found here, but I have summarized the steps below):
      1. Head over to Active Directory and create a new user
      2. Head over to the SQL Server
      3. Right click on Security->Logins and click New Login…
      4. Enter in your AD account you just created
      5. Click on User Mapping
        1. Check both the LcsCDR and QoEMetrics databases
      6. Click OK
        1. Do the following for both the LcsCDR and QoEMetrics databases
          1. Expand the database, expand Security, export Users
          2. Right click on the user you mapped to the database and click Properties
          3. Check ReportsReadOnlyRole and click OK
  37. Enter in the User Group you want access to run reports.
    1. This group is a list of users who have access to actually run the reports/will point and click on reports.
  38. Click Next, you should notice the following info when it starts configuring, that is normal:
    1. The following URL will be used for deployment: https://myserver.mydomain:443/ReportServer SQL Server logon credentials for “mydomain\myuser” already exist. Use the existing logon credentials. “[QoEMetrics]” role “[ReportsReadOnlyRole]” has already assigned to “mydomain\myuser”. “[LcsCDR]” role “[ReportsReadOnlyRole]” has already assigned to “mydomain\myuser”.
  39. Click Finish (Assuming all went OK) 🙂
  40. Head over to your Lync admin panel (web GUI)
  41. Click on Monitoring and Archiving
  42. Select Global and click on Action and select Enable CDR
  43. You can change any other settings in here to your preference at this point.
  44. Head over to your reports page. https://yourdomain/ReportServer
  45. Click on LyncServerReports
  46. Click on Reports Home Page

If you see the Monitoring Server Reports page with the Lync 2010 logo in the top left corner, get up, celebrate, and pat yourself on the back! 🙂

Other thoughts: The first time I deployed this, I ran into a ton of errors.  I have documented many of these issues and other issues that you might run into during your deployment.  Hopefully you don’t run into any, but if you do, hopefully they help you get up-and-going again.
