I have a problem with my home network. The two computers in my network, A and B are connected via LAN cable without going through any router or ports. Both operate using MS Windows XP SP1. Nevertheless, the funny thing is that computer A, although having higher levels of security protection with firewalls as compared to the other system, cannot access the shared files and folders on computer B, which has ironically no firewalls whatsoever. The error message when I try to access Computer B from Computer A reads as follows:
Computer A\\ is not accessible. You might not have permissions to use this network resource. Contact the administrator of this server to find out if you have access permissions.
Logon failure: the user has not been granted the requested logon type at this computer.
On the other hand, Computer B can access totally Computer A.
What's the problem and how can I solve it? TQ.
