This article is intended for system administrators with at least an intermediate skill level working with Windows Server® 2012 operating system operations and administration.

You cannot launch an Internet Information Services (IIS) web farm by using the Microsoft® Web Farm Framework (WFF) in IIS8. Microsoft says that they are not abandoning the WFF technology, but they have not provided a solution.

However, this article shows you how to use Web Deploy and PowerShell® scripts to keep your web content synced while you manage it from a single master server. This process is not as quick or GUI-friendly as WFF, but it uses official Microsoft technology and keeps your web content synced.


To get started, create a new user account with the same username and password on each server in the farm. Make this account a member of the local Administrators group on each server. On the primary server, add this account to the Log On As Batch security setting by navigating to Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment. This exercise uses the following credentials:

Username: SyncMan
Password: P@ss1234

On each of your secondary cloud servers, create a Windows Firewall rule to allow ALL TRAFFIC from the primary server (master).

On the master server only, perform the following actions:

  • Create a common directory, such as C:\WebSync, to store the Web Deploy templates.

  • Open a PowerShell window and execute Set-ExecutionPolicy Unrestricted. When prompted, type Y and press ENTER.

To simplify your scripts, modify C:\Windows\system32\drivers\etc\Hosts to include a listing for each node, matching its internal IP address to an easy host name, such as WEB2.

Web Deploy

Download Web Deploy from IIS and install it on each server in the farm.


Use the following steps to create two scripts on the master server.

Batch script

Open a new Notepad file, and paste the following code into the file:

"powershell.exe -command C:\WebSync\WebDeploySync.ps1"

Save this file as C:\WebSync\WDSync.bat.

PowerShell script

In a new Notepad file, enter the following lines:

add-pssnapin wdeploysnapin3.0

New-WDPublishSettings -ComputerName [MasterServerName] -AgentType MSDepSvc -FileName c:\WebSync\[MasterServerName].publishsettings

New-WDPublishSettings -ComputerName [SecondaryServerName] -AgentType MSDepSvc -FileName c:\WebSync\[SecondaryServerName].publishsettings -UserID SyncMan -Password P@ss1234

Sync-WDServer -SourcePublishSettings c:\WebSync\[PrimaryServerName].publishSettings -DestinationPublishSettings c:\WebSync\[SecondaryServerName].publishSettings

Note: The preceding code reflects a 2-node setup. If you want to have more secondary nodes, you need to add another New-WDPublishSettings -ComputerName [SecondaryServerName]... line for each secondary server and add a new Sync-WDServer.. line that syncs the primary server to each subsequent secondary server.

Save this file as C:\WebSync\WebDeploySync.ps1.

Schedule the scripts

Set up a scheduled task to run the scripts at a semi-constant rate to ensure that your web content stays synced across the nodes. This task needs to be set up on only the master server. The task should have the following characteristics:

  • Use the SyncMan credentials that we specified earlier.
  • Run even when the user is not logged on.
  • Be a daily task that runs every 1 minute for a duration of 1 day to ensure that it will run indefinitely at a 1-minute intervals.

Use the following steps to schedule the task:

  1. To access the Task Scheduler, navigate to START -> Administrative Tools -> Task Scheduler.

  2. Select Task Scheduler Library in the left column.

  3. Click on Create Task in the right-hand Actions pane.

  4. On the General tab of the Create Task box, enter a descriptive Name for the task, enter the SyncMan credentials by clicking Change User or Group, and select Run whether user is logged on or not from the radial list. Select Windows Server 2012 from the Configure for drop-down list.

  5. On the Triggers tab of the Create Task box, click New.

  6. In the New Trigger box, select Daily from the radial list, and choose a start time of 5 or 10 minutes in the future. Set Recur every to 1. In Advanced settings, check Repeat task every and enter 1 minutes in the text box. Leave for a duration of set to 1 Day. (Note: “1 minutes” is not a typo. Ensure that you leave “minutes” plural).

  7. On the Actions tab of the Create Task box, click New.

  8. In Edit Action, select Start a program, and in Program/script, enter C:\WDSync\WDSync.bat. Click OK.

  9. On the Conditions tab of the Create Task box, uncheck all the boxes.

  10. On the Settings tab of the Create Task box, check Allow task to be run on demand, and leave all other check boxes cleared. In the If the task is already running, then the following rule applies drop-down list, select Run a new instance in parallel.

  11. Click OK in the Create Task box.

To ensure that the task runs, click Enable All Tasks History in the Actions pane on the right side of the Task Scheduler. After the task starts running, you can highlight it and click on the History tab to ensure that it is running regularly every minute as shown in the following image:


After the script and scheduled task are complete, you can test this by making a change on the master server and ensuring that the change shows up within IIS on the secondary servers. You should also be able to make a change on the secondary servers in IIS or in the directories controlled by IIS and see that your change on the master server is overwritten in a minute or less.
