Pc is a HP Pavilion dv6 Notebook PC The problem is a follows Windows 7 laptop have lost access to my shared folders on my windows XP desktop. My windows XP desktop can see the shared folders on my windows 7 laptop. Also the function \\11.11.11.11\ doesnt work "ip is made up. and is in the allowed range" Things I know. I got this problem the first time about 4-5 months after I bought the Laptop. The problem can be fixed by using a restoration point. the amount of time from the restoration point use decides when the problem starts again. I reinstalled the PC and 4-5 months later the problems come back. I now have a Restoration point that takes me back 6 days before the problem comes. And I have tested it. The way the error occurs makes me suspect that there is a timer, somewhere triggering it. Diagnostic. Windows 7 can not find any problems Internet works. Pinning works. Restoration shows that only one program have been change. (Microsoft Remote Desktop Services (printer) 06/21/2006 6. 1. 7600. 16385) Any help or thought is appreciated
