1) seems to be replacing '(', ')' and '/' characters in the network adapter name with '[', ']' and '_' respectively. Is there a list of characters that will be replaced by WMI ? 2) The Name property seems to have the format "<adapter_name> - <friendly_name>". Is this documented somewhere ? eg. The if the adapter name is "ABC(T) 10/100 Network Adapter" the Name property is: ABC[T] 10_100 Network Adapter - Packet Scheduler Miniport
