Can't access nas from windows 11 pro

My Cloud OS 5 My Cloud EX

Hello everyone, I have a problem with my MyCloudEX2Ultra. Since I sent my PC in for repair, it was formatted, and they reinstalled Windows 11 Pro. However, since then, I haven’t been able to access the NAS, receiving the following error message:

“Check the spelling of the name. Otherwise, there might be a problem with your network.”

However, I can access it without any issues from all my other devices (laptop, Android phone, and iPad).

I have already tried the following resolution:

Configure your third-party SMB server device to require a username and password for SMB connections. If your device allows guest access, any device or person on your network can read or copy all of your shared data without any audit trail or credentials.

If you can’t configure your third-party device to be secure, you can enable insecure guest access with the following Group Policy settings:

  1. Open the Local Group Policy Editor (gpedit.msc) on your Windows device.
  2. In the console tree, select Computer Configuration > Administrative Templates > Network > Lanman Workstation.
  3. For the setting, right-click Enable insecure guest logons and select Edit.
  4. Select Enabled > OK.

But it didn’t work.

What do you recommend?

  1. Disable the SMB client signing requirement:

a. On the Start Menu search, type gpedit and start the Edit Group Policy app (i.e. Local Group Policy Editor). If you are using Home edition, skip to step 8.

b. In the console tree, select Computer Configuration > Windows Settings > Security Settings> Local Policies > Security Options.

c. Double-click Microsoft network client: Digitally sign communications (always).

d. Select Disabled > OK.

Is NETWORK DISCOVERY (in SETTINGS/NETWORK & INTERNET menu of W11) set to ON?

It worked! Thank you!
