\"How<\/p>\n

When I try to connect to the NAS on Windows 10, I get "Access not possible"<\/span>.<\/p>\n

The NAS is up and other PCs can connect<\/span>, but one PC doesn't even ask for the password.<\/p>\n

What is the reason why only a specific PC cannot be explained to NAS?<\/p>\n

In order to solve such troubles, this time we will introduce "How to solve "Access failure" when connecting to NAS from Windows 10<\/span>".<\/p>\n

You can understand \"How to solve \"Access failure\" when connecting to NAS from Windows 10\". Then you don't concern about NAS trouble.<\/span><\/p><\/div><\/div>\n

<\/p>\n

<\/br><\/p>\n

Cause of "Access failure" to NAS<\/h2>\n

\"\"<\/p>\n

If you try ping<\/code> to the IP of the NAS and it does not come back, other PCs cannot connect because there is no network route in the first place.<\/p>\n

The reason why other PCs can connect but only a specific PC cannot connect is from SMB1.0 client is disabled<\/span><\/strong>.<\/p>\n

The SMB1.0 client has security issues and is disabled by default<\/span> after the initial setup of Windows 10.<\/p>\n

However, if the NAS side only accepts connections with SMB1.0, you will not be able to connect unless you enable SMB1.0.<\/p>\n

<\/br><\/p>\n

However, SMB1.0 is an old system and has vulnerability<\/strong>. Better not<\/span>.<\/p>\n

\nEternalBlue is a security flaw in the way "Windows SMB1.0 (SMBv1)" servers process certain requests.<\/p>\n

<\/br><\/p>\n

So buy a new NAS<\/span> if possible.<\/p>\n

<\/br><\/br><\/p>\n

How to enable SMB1.0 client<\/h2>\n

\"\"<\/p>\n

Enabling SMB 1.0 is not recommended, but if you still need to access your old NAS, you'll have no choice but to enable it temporarily.<\/p>\n

To enable the SMB1.0 client, open the Windows function setting screen by the following operation.<\/p>\n

Then check SMB1.0\/CIFS file sharing support<\/code> to enable it.<\/p>\n

    If you are reading this article, you probably already own a NAS.<\/p>\n

    NAS and PC are convenient enough, but If you have a small PC, you can periodically retrieve and write files to the NAS from the outside<\/span>, so Better if you have a small PC<\/span>.<\/p>\n

    There is an article about recommended models for small PCs, so please take a look at that as well.<\/p>\n
