Newly purchased a computer, so I purchased a router to share ADSL Internet access with the old computer network. If you don't want to network, the old computer (installed 2000) cannot access the new computer shared file, even the printer can not be used (on XP new computer). So I checked it, I checked it for a long time. Since now: 1. On the guest account; 4. Under XP "View", "Use Simple File Sharing"; 5, firewall problem; 6, is it in the same group, user problem; 7, "network access: local account sharing and security mode" group The strategy is "Live" or "Classic"; 8. Is the property of shared files for read-only, whether or not to add guests in the permissions; Account: Use the local account of the blank password .... Console login! Use it! 10, in the data clip option? Do you have any of the default sharing? Hook? Remove 11, agreement; 12, even if you have tried it, you don't necessarily solve the problem! tired! ! ! ! !
