Need help with UNC

I'm spying on a folder on a shared drive. I can't actually get to the shared folder ( FindFirstNotificationChange returns -1 ). I'm using \\server\drive\vol\user\directory and I always get -1

here's the code

This works fine


Ret = FindFirstChangeNotification("c:\Nicolas\Test", false, FILE_NOTIFY_CHANGE_FILE_NAME)




But this doesn't


Ret = FindFirstChangeNotification("\\server\vol\user\Nicolas\Test", false, FILE_NOTIFY_CHANGE_FILE_NAME)




Any idea ?

Thanks

Nicolas
