You can use the Windows Networking Functions "
WNetAddConnection2" and "
WNetCancelConnection2" to map the drives. You can make a connection to a network resource by using the "
WNetAddConnection2" function and can cancel an existing network connection by using the "
WNetCancelConnection2" function.
