I connect 2 computer with crossover cable but i can't share folders in both system and i just be able to see their library and sharing the printer. what is the problem?

Let's assume that you log on to PC1 as eHamid/password. You must now make sure that PC2 has a matching acount eHamid/password and that the password is not blank. _________________________ If this response resolves your problem, please click "Propose as answer" so that the thread can be closed.

Thank you for your answer. I create the same account in both PCs. My problem almost solved but now I have another problem. I connect Desktop Computer(server) and Laptop. Now I just be able to share Folders, which are in DC( server) and i can't share folders, which are in Laptop. How Can I solve this problem?

You appear to be running in a domain environment. If so then your ability to access shares that reside on your server depends on your method of authentication, that is local authentication or domain authentication. Your network administrator is the best person to resolve this issue for you.
