Win7 with the Vista , XP and so the old system cannot access each other share

It's possible that we've all come across a similar problem inWin7LAN system under the system, there is no access to each othersharedThe problem with the file.

Windows 7 uses a different Windows encryption than the old versionsharedWay, which in improving the networksharedSecurity, it also brings obstacles to Windows shared visits between different versions. Sometimes, though we can see each othersharedFiles, but many times, users can only stay on the "discovery" level, unable to copy or cutsharedFile.

In order to simplify too much description, I suggest you first understand the "Xp/windows7 file cannot exchange visitssharedProblem. "

Typically, if you have confirmed that network discovery and files and printers are enabled for the current systemshared"and has turned off the password-protectedshared”。 (In the Network andsharedCenter → AdvancedsharedSettings, but in the exchange of visitssharedFile, it is still not accessible, most likely because the non-Windows 7 version of the system does not support 128-bit encryption.




Open the Control Panel → Network andsharedCenter → AdvancedsharedSettings, in the filesharedConnection area, modify the system default selection to enable for devices that use 40 or 56-bit encryptionsharedFile ".



Enable in Windows 7 for devices that use 40 or 56-bit encryptionsharedFile

After the modification is complete, save the settings to exit.

Little knowledge, what is 128-bit encryption?

128-bit encryption does not have a fixed noun interpretation, general, 128-bit encryption is common in server aspects. It is clear that Microsoft has introduced it to non-server users to improvesharedThe security of the file.

Typically, server certificates are divided into two levels based on encryption strength, which is low encryption level and high encryption level. Low-end encryption strength is 40-bit or 56-bit, high-end encryption strength is 128-bit or 256-bit. At the server level, users with low-end encryption can access high-end encryption, not entirely dependent on themselves, but also by the customer operating system, browser version, network server (the certificate used) these three aspects. For example, even if the user's current system does not support 128-bit-strength encrypted links (that is, high-end encryption), even if the server certificate can support 128-bit, the client will automatically reduce the encryption strength
