Solution for "No network provider accepted the given network path"
When you try to access a network path (FQDN) by “start”-“run”-”\\machine_name\share_name”, and meet error message “No network provider accepted the given network path.” But when you open the Command Console (“start“-“run“-“cmd“), you can ping that machine successfully by using the FQDN.
