WD NAS Can’t Be Seen In Windows? Here Are The Solutions!

You may be wondering why your WD NAS is no longer visible in Windows 10.

Where did it go? How do you get it back?

Find out why your WD NAS cannot no longer be seen in Windows, and what are the solutions!

 

WD NAS Can’t Be Seen In Windows : What Happened?

You may have been using your WD NAS for some time, but one day, its network share – the “drive” that you directly access – can no longer be seen in Windows 10.

The NAS links in Windows File Explorer will only lead you to the login page for the WD NAS management page, not the actual drive where you can directly read, copy, write or edit your files.

All these NAS issues are happening because Microsoft disabled the Network Browse function from Windows 10 v1709 onwards.

The problems started after Windows 10 Fall Creators Update 1709, which :

The Computer Browser service relies on the SMB 1.0 protocol to discover network devices and display them in the Windows Network Neighbourhood.

Disabling SMB 1.0 breaks the Computer Browser service, so it is automatically uninstalled and your NAS drives “disappear” from Network Neighbourhood.

Disabling guest access prevents guest or public access to your NAS drives, even to folders you specifically set to allow for public access. Hence, the Public folder they had access to earlier “disappears”.

 

Why Did Microsoft Disable Those Network Features?

The SMB1 network protocol was first implemented in Windows back in 1992, so it’s old… very old.

It’s so old that it lacks encryption. Everything transmitted via SMB1 can be captured and read, and even modified, by any attacker who gains access to the network.

Guest logins even on SMB2 do not support standard security features like signing and encryption. This makes them vulnerable to man-in-the-middle attacks.

That’s why Microsoft (finally) disabled them both, starting with the Windows 10 Fall Creators Update 1709.

 

WD NAS Can’t Be Seen In Windows : Before We Start…

Preliminary Step #1 : Update Your NAS

Before you do anything, you should log into your WD NAS management system and update its firmware, in case it’s not already set to automatically update.

Updating its firmware will ensure that your NAS supports at least SMB 2, if not SMB 3 as well.

WD NAS Windows URL macOS URL
My Cloud EX2100 http://wdmycloudex2100 http://wdmycloudex2100.local
My Cloud DL2100 http://wdmyclouddl2100 http://wdmyclouddl2100.local
My Cloud EX4100 http://wdmycloudex4100 http://wdmycloudex4100.local
My Cloud DL4100 http://wdmyclouddl4100 http://wdmyclouddl4100.local

Preliminary Step #2 : Use A Higher SMB Protocol

Then, enable the highest SMB protocol your WD NAS supports (Settings > Network). Set it to SMB 3 if possible.

This will ensure that both your WD NAS and your network support the most secure network protocol possible, for your security.

 

WD NAS Can’t Be Seen In Windows : The Solutions!

Best Solution : Map Your WD NAS By Device Name

The best way is to manually map your WD NAS by its device name. This lets you use the more secure SMB2 or SMB3 network protocols, with direct access to your files as usual.

  1. Determine your WD NAS network path, which is based on the device name.If you changed your WD NAS device name to TechARPCloud (for example), the network name will be \\TechARPCloudHere is a list of default network paths for different WD NAS :
WD NAS Default Network Path
My Cloud Home \\MYCLOUD-last 6 digits of serial number
Example : \\MYCLOUD-123456
My Cloud Home Duo
My Cloud \\WDMYCLOUD
My Cloud Mirror \\WDMYCLOUDMIRROR
My Cloud Mirror Gen 2
My Cloud EX2 \\WDMYCLOUDEX2
My Cloud EX2 Ultra \\MYCLOUDEX2ULTRA
My Cloud EX4 \\WDMYCLOUDEX4
My Cloud EX2100 \\WDMYCLOUDEX2100
My Cloud EX4100 \\WDMYCLOUDEX4100
My Cloud DL2100 \\WDMYCLOUDDL2100
My Cloud DL4100 \\WDMYCLOUDDL4100
My Cloud PR2100 \\MYCLOUDPR2100
My Cloud PR4100 \\MYCLOUDPR2100
  1. Open Windows File Explorer and click on Network on the left pane.
  2. Key in the network path of the WD NAS, which is based on its device name. Make sure you include \\ before the network path.

  1. You will be asked to key in a user name and password.
    This can be the administrator’s login, or the login of any registered user of your WD NAS.
    Remember – Windows 10 no longer allows guest logins or public access. So you will need to create a password-protected account even for guests to use.

  1. Once you successfully authenticate your user name and password, the network shares of your WD NAS will become visible in File Explorer under Network!You can stop here, but you will need to keep keying in the network path and login to access your NAS every time you boot into Windows.

  1. For more convenience, you can create a password-protected Private Share.Start by right-clicking on a network share from your WD NAS and select Map network drive…

  1. Select a drive letter for the network share.
    Check Reconnect at sign-in if you don’t want to automatically log into the drive.
    Then click Finish to map the drive.

That’s it! If you expand This PC in Windows File Explorer, you should now see that the WD NAS network drive has now been mapped by its device name!

 

Alternate Solution : Enable Network Discovery Without SMB1

This Windows 10 workaround can be used if your WD NAS supports SMB2 or SMB3 and you prefer not to map the network drives.

  1. Go to Windows Services.
  2. Start these two services :
    Function Discovery Provider Host
    Function Discovery Resource Publication
  3. Set the Startup type for both those services to Automatic (Delayed Start).
  4. Open Windows File Explorer and go to Network.
  5. When prompted, enable Network Discovery.

Your WD NAS shares should now be visible in Windows File Explorer.

 

Worst Case Solution : Enable Network Discovery Without SMB1

This should only be attempted if your WD NAS simply cannot support SMB2 or SMB3, and can only use SMB1.

  1. Go to Control Panel > Programs.
  2. Click on Turn Windows features on or off.
  3. Expand the SMB 1.0/CIFS File Sharing Support option.
  4. Check the SMB 1.0/CIFS Client option.
  5. Click the OK button.
  6. Restart Windows 10

After Windows 10 restarts, your WD NAS shares should now be visible in Windows File Explorer.

ASUS AiProtection On ASUS Routers Revealed

1 December 2016ASUS today announced that during the first half of 2016, its ASUS AiProtection network security software — an integral feature of selected ASUS routers — neutralized almost five million internet-based threats and nearly 150 million blocked attempts to visit websites with hidden security threats. This represents a daily average of approximately 1.5 attacks and risks neutralized on each AiProtection-enabled router.

 

ASUS AiProtection

AiProtection is a router-based security software developed in response to the security needs of modern home networks. It incorporates advanced technology from Trend Micro — including the first consumer implementation of commercial-grade intrusion prevention technology — to detect, block and neutralize security threats on home networks.

AiProtection can prevent infected devices — even those without anti-virus capabilities, such as Internet of Things (IoT) devices — from sending personal information to malicious web servers. The proactive protection given by AiProtection is also a key feature that helps defend the network from devices with missing or out-of-date security protection.

With the recent evolving types of threats associated with ‘smart’ IoT devices, home routers are increasingly the focal point of network security. Traditional infection vectors such as viruses and malware are now augmented by more insidious cyber-threats, including ransomware, phishing and other social engineering attacks, which are aimed at stealing or extorting money or compromising users’ personal data.

AiProtection actively provides secured home network through commercial-grade technology, actively blocking malicious websites, connections between infected devices and malicious servers, and providing home network security auditing.

Commercial-grade technology

ASUS AiProtection includes a commercial-grade intrusion prevention system (IPS). This features a sophisticated Deep Packet Inspection (DPI) engine to analyze the contents of all data packets entering or leaving the home network, and block any malicious or suspicious packets, regardless of the device they originated from.

AiProtection is updated automatically, with both scheduled and rapid-reaction updates ensuring the most up-to-date protection for users’ devices.

During the first half of 2016, analysis of ASUS AiProtection activity on the installed base of ASUS routers indicated that over almost five million internet-based attacks were prevented, which is an average of over 1.5 attacks per day on each AiProtection-enabled router.

Blocks malicious websites

ASUS AiProtection incorporates the cloud-based Trend Micro Web Reputation Services (WRS), which intercepts URL requests and checks them with the WRS database before allowing access. If the URL is found to be malicious, it is blocked, protecting the user from potential threats.

According to Trend Micro, 76 percent of ransomware is delivered via spam email. Links to malicious sites contained in such emails, or posted on other unsafe websites, are one of the main sources of ransomware infections.

The scale of the problem can be seen from the fact that on a single day[2], over 800,000 requests to access malicious sites were successfully blocked by AiProtection.

Blocks infected devices

Infected devices connected to a network can function as gateways that allow other devices on the network to be infected, or help relay private data to external servers. ASUS AiProtection detects infected devices and prevents them from compromising the local network. It also severs any suspicious external connections. Users are immediately notified via email if this happens, so they can take appropriate action.

Easy home network security auditing

ASUS AiProtection also offers users an easy way to check the overall security of their home network. It scans 14 critical router settings and alerts users to potential risks, as well as recommending ways to fix the problems.

SonicOS 6.2.6 Advanced Protection Now Available

Kuala Lumpur, 1 August 2016SonicWALL customers observed dramatic increases in their network security during the technical preview of SonicWALL Capture Advanced Threat Protection Service.

 

Dell SonicOS 6.2.6

With the announcement of the general availability of SonicOS 6.2.6 firmware, SonicWALL Capture is the industry’s first multi-engine sandbox that enables customers to block suspicious files until a verdict is reached. Additionally, SonicOS 6.2.6 features an enhanced Content Filtering Service that gives organisations the power to easily enforce protection and productivity policies to control access to inappropriate or unproductive web content.

Available for use with SonicWALL TZ, NSA and SuperMassive 9000 series firewalls, SonicOS 6.2.6 with SonicWALL Capture protects customers from today’s most advanced threats, including zero-day attacks.

Malicious code authors have developed techniques allowing malware to detect the presence of existing sandboxes and use this information to evade detection. To combat these techniques, SonicWALL Capture utilises three technically different cloud-based threat analysis sandboxing engines, making evasion almost impossible. Capture also has the ability to accept the broadest range of file sizes and types and can be configured to block suspicious files from entering the system until a verdict is reached.

Angel Torres, CIO of Credit Services, Inc. reports, “The new SonicWALL Capture service is another key addition to the suite of security tools that help us battle the new challenges that we face on a daily basis. By providing this new service, it feels like we have a partner working with us in the fight to keep our system secured. By preventing malicious files from entering our system, it helps keep our clients and our company more secure from new threats as they emerge.”

“We did some evaluations of other sandbox solutions, but SonicWALL Capture was the easiest to implement and most cost-effective to license and manage. Because it’s offered as an upgrade to our firewall and only requires a firmware update, testing and eventual deployment into a production environment was really easy. We are looking at utilising this at our other sites as we focus on multiple, layered approaches to security,” stated Zachary A. Radke of Santa Fe Senior Living.

 

SonicWALL Content Filtering Service 4.0

The new SonicWALL Content Filtering Service 4.0 available in SonicOS 6.2.6 enables IT to enforce protection and productivity policies and block inappropriate, unproductive and illegal web content from the network. Key new features in this version include:

[adrotate banner=”4″]

Block-page override, Bandwidth Management and Confirm actions ‒ In addition to the current allow and block methods, CFS 4.0 also offers block-page override (passphrase), bandwidth management, and confirm actions, giving administrators additional controls to individual domain categories. These five methods are configurable at the policy level (versus a global setting). This can enable educational institutions, for example, to personalise the teaching experience for specific schools, classrooms or groups of users behind a firewall, empowering teachers and IT administrators to facilitate a better and more productive learning experience.

YouTube Restricted mode ‒ Similar to parental controls, YouTube Restricted mode helps inhibit the search for, or access to, inappropriate videos based on YouTube’s proprietary technology.

“The SonicWALL CFS version 4.0 has given us more power over the filtering system by allowing us to control the priority of the policies,” said George Morris, IT Administrator at Peru Community Schools. “This lets us set multiple allow or deny rules and have users with multiple policies, and still maintain complete accuracy of the outcome. We view these enhancements as proof that the best just got even better.”

 

SonicOS 6.2.6 Availability

SonicWALL SonicOS 6.2.6 will be generally available August 1. SonicWALL Capture ATP Service will be available for SonicWALL SuperMassive 9000 series, NSA firewalls and select TZ firewall models August 1. Current customers should contact their account representatives.

F-Secure Offers Journalists Free Freedome Privacy & Security App

May 3, 2016 – Today is World Press Freedom Day – an event designed to highlight the importance of free speech as a human right. Having free speech lets journalists investigate problems happening all over the globe, often at the expense of their own privacy, or even personal safety. So F-Secure, a Finnish cyber security company, is taking steps to help journalists safeguard their right to free speech by offering them free VPN subscriptions.

According to Reporters without Borders’ 2016 World Press Freedom Index, Finland has the freest media in the world, making it fitting that this year’s World Press Freedom Day event is being held in the Finnish capital of Helsinki. However, the report also noted the overall freedom of press is in a global decline, and dropped by 13.6 percent since 2013.

“Free speech is something nurtured by some governments, but many see it as a threat when mobilized in an institution like the media,” says F-Secure Cyber Security Advisor Erka Koivunen. “And even though technology has given governments unprecedented surveillance capabilities, it’s also given people ways to protect themselves. Encryption is probably the best tool available to journalists if they want to conduct investigatory work without suffering reprisals from oppressive governments and institutions.”

Journalists can use VPNs such as F-Secure Freedome to encrypt their communications, change their virtual location, and block malicious websites and online tracking attempts. And to help make using encryption more accessible for journalists, F-Secure is offering free 12-month subscriptions for Freedome to journalists until May 15.
