Computers under the XP system cannot access shared folders in Windows 7. Although some can see the shared directories under Windows 7, once they enter the directory, they will be prompted that they do not have access permissions.
Solution:
Go to the "Network and Sharing Center" to set up and turn off Windows Firewall. Although there is a risk of insecurity in doing so, in order to achieve mutual access between different systems, it can only be done as a last resort.
After turning off Windows Firewall, the next step is to enter the "Advanced Settings" on the left side of the firewall settings interface and modify the "Inbound Rules" and "Outbound Rules". In these two rules, find the "File and Printer Sharing" option respectively, and set all its options to "Allow all connection".
After completing the above settings, enter the "User Account", open the "Guest" account, and enable the corresponding sharing function in the system service. At this point, the sharing settings are almost complete. The last step is to set the corresponding shared folder. If you are familiar with XP sharing settings, you can basically operate the following settings very conveniently. The concept of setting sharing in Windows 7 is almost the same as that in XP. The only difference is the setting path.
The first step is to select the folder you want to share, right-click and select "Properties", select "Advanced Sharing" in the "Sharing" tab, and check the box in front of "Share this folder", and then select "Permissions" Click "Add" - "Advanced" - "Find Now" in sequence. Then select "Everyone" and "Guest" in the search results and confirm.
The above steps can basically solve the problem of 99% of XP being unable to access Windows 7 shared folders. Of course, it is not ruled out that access exceptions may still occur through the above methods. For this reason, it is recommended to temporarily turn off additionally installed anti-virus software or third-party network firewalls such as Skynet to prevent other network firewalls from blocking access.
