I am facing a problem with file sharing in Windows Vista Home Premium. My wife is having a laptop which is having the same OS in it. I want to share some files so that she can also access it on her laptop. But somehow in network discovery my laptop is not at all visible. We are on the same workgroup. There is no router no lan nothing. The laptop is connected with ethernet port. While sharing I got the error saying that your folder cannot be shared. The issue lies with the file permission. I had modified the same but still the problem is same. I thought the issue was due to network path. I have Norton installed on my system. Does that is the cause of this problem.
