PROBLEM
When attempting to join an ArcGIS Server machine with a different .NET Extension Support feature, the following error is returned:
Error:
Failed to join the site <site1URL>. The state of the .NET Extension Support feature configured on machine <Site2URL> does not match the site running at <Site1URL>. All machines in a site are required to have the same .NET Extension Support configuration.
The .NET Extension Support configuration on the original ArcGIS Server machine does not match the configuration on the new machine being added to the site.
Ensure that the .NET Extension Support feature on the new ArcGIS Server machine matches the configuration of the existing server before joining it to the site.
