In this short article, I will tell you about Shared Configuration in IIS. Before we start, first thing that you should do is backup the following configuration files for your sites on both servers, administration.config and applicationHost.config.The default location for that files are in C:\Windows\System32\inetsrv\config.  If you got an error you can use the files to restore the configuration back to its original state. 

1. Now, from server1 in IIS Management chopse the server name and on the right Window pane under Management click the “Shared Configuration” icon like the picture below:

2. Next, on the Actions pane select “Export Configuration” as shown on the picture below:

3. Copy the files to a folder location on server2 (administration.config and applicationHost.config)
4. Now, Open the Shared Configuration icon in IIS Manager for server2
5. Tick on the box to “Enable shared configuration”
6. Now, Enter the path to the exported configuration files on server2

8. Close and open up IIS Manager, choose the server name, click the Management Service icon and choose Restart under the Actions menu (you may additionally choose to run iisreset at the command line)

Now make sure the sites are in place. you'll disable “Shared Configuration” if everything is setup properly. when you go to disable “Shared Configuration” you will be prompted to choose “Yes” if yo wish to copy the new configuration back to the default folder location or select “No” if you do not want to import the new configuration however instead revert back to your original configuration. Select “Yes” to overwrite your original file configuration with the new configuration.  Check the Event Viewer to assist troubleshoot any problems you run into with the sites.
