When attempting to add a new server within the Query tool, upon clicking on the Add button (see diagram 1), a critical failure occurs (see diagram 2).    This error occurs because of a corrupted server.xml file.    By clicking on the Ignore button, the system will automatically rebuild the server.xml file, which is located C:\Users\xxx\AppData\Local\Wonderware\ActiveFactory\Servers.xml.    

The error should resolve itself allowing the server to be added to the Server List.
