Network Drive Control can let you toggle off & on, the automatic mapping of a drive, even if you log in while the PC is connected to network that has a drive mapping configured for it. 


If the checkbox in the "Manual" column for a given mapping is checked as shown for Drive #4 below, then NDC will ignore the mapping during login. The drive can still be mapped manually by selecting the line and using the "Connect Drive" or using the context menu that appears when you right-click on the line.


When you toggle the checkbox, the change is not saved & it does not go into effect until you either click the "Refresh List" button or close the Network Drive Control Console.
