Analyze the problem:
1. First sense: Win7 system sharing is not set up correctly (install the online steps to join a workgroup, open a network share and file and printer sharing, turn on background services, and firewalls), but the same problem
2. Forget to consider a point: is not the problem of XP system, Win7 to the LAN share need for new services or protocol support, XP is not installed, and finally it is necessary to further XP local connection to add a protocol, on the normal
Two points to do, the first step is to start from Win 7, open the relevant background services
The second step is to start with XP and add a protocol to XP.
(It seems that we are dealing with problems that need to be considered from both sides of the relevant matter, and that the problem may be multiple places, and only a few words will let us go astray.) Nonsense do not say, look at the specific process.
