Ok, here's my problem. I have two computers (I will refer to them as A and B in this topic). A is running Windows 7 Starter, and B is running Windows XP Professional SP3. I was able to successfully set permissions and credentials on B so that on A or any other computer you will have to enter an administrator's username or password to access it's shared files. It loads and operates just fine on A. But now, I want to share A's files to B and B won't open them. It won't ask for my credentials, so A assumes I'm logging on under my account on B, which does not have administrator privileges on A. This is probably a really stupid question, but how would I get B to ask me for my A credentials?
