  1. Can't access NAS by name

    Yesterday I did a clean (re)install of Windows 10. All seemed ok, but today I cannot access a NAS disk by name. I can access it by IP address, and nslookup correctly resolve both name and addresses. But if I try to access \\MyBookLive (I know, - a cleverly original name.) - I get an error saying "Windows cannot access \\MyBookLive", giving an error code 0x80004005.

    For the time being, I've mapped the IP address so I can access the drive, but I recall getting security warning popups in the past when I've done that so I hope this is temporary. And the IP address is set DHCP so I can't guarantee it will stay the same.

    Any idea how to resolve this?

  2. homegroup with windows 10 & windows 7.

    On the windows 8.1 machines: When I first tried to access the NAS network credentials were asked for. I signed in with the user names and passwords established in the NAS and checked for them to be saved. This provided me with seems access. By the way
    the machine already saw the NAS on the network. The NAS was is setup as DHCP, not static.

    As for Windows 10: The machine doesn't see the NAS on the network (the NAS has all the same settings and passwords). Only sees it after a reboot, power cycle or factory reset of the NAS; for a limited time and then it can't find it again. When I accessed
    the NAS through the app on the win10 machine, network credentials were asked for given and saved, access to the NAS was given. When win10 sees the NAS, I have access to it.

    Therefore the credentials must be established.

    If there is something extra to do in win10, I'm not aware of it. If the NAS has to be a static IP, I'm not aware of it. If you mean something else or have further direction, like how to create said network credentials, I'm reading.

    Windows 10 can't access NAS by IP \\ or by name \\NASName - HELP!

    This started several weeks ago. I have a Buffalo Storage 1TB NAS that has been working for a couple years, and is still accessible by other systems in my house.

    However, my main PC all of a sudden couldn't access the drive by it's network name (\\BigBuffalo). Now today, I can't even access it by its IP address: (\\

    To be clear, I can access the drive via browser, and other systems in my house have no issues accessing the drive. I've seen multiple fixes that simply don't work. PLEASE HELP. I need access to my NAS badly!

    Can't access NAS by name

    WD has some useful applications. Try WD quickview, it will give quick access to state of drive and also a way to go to drive.
    Just a suggestion.

    Also host name may have changed with some firmware updates.

  5. The WD application that maps drives seems to use the address rather than name of the server. Two other PCs are accessing the server by name so I'm pretty sure the name hasn't changed. (But that doesn't mean I used the right name or specified it correctly in the Map process.) I'll dig around some more.

    Do you have network discovery turned on? New installations of Windows sometimes needs few days to get all connectivity...
    AndreTen, Apr 16, 2016
  7. Yes, I have network discovery turned on ... at least on the place you showed. I don't know about other options I might have wrong. In a detail display of the Network part of the file explorer display, Windows says it uses SSDP to discover the NAS server. I have no idea if that's what I should be using (or how to change it if it's not right).

    Can't access NAS by name

    It most probably doesn't matter.

    Can you connect to your WD and check name? I can connect to mine with clicking on MyBookLive icon in windows explorer, or by giving IP number in browser. Check for name setting (if you have change it) or for quick solution to give it static IP number.

    Edit: also download and run WD Discovery app from WD site. It may help.

  10. I've now read that post - I had missed it. I'm a little reluctant to mess with the LAN Manager Security Level because
    • it worked on the now problematic PC before I did a clean reinstall of Windows 10 (although sometimes not right after a reboot)
    • it works correctly on 2 other PCs - 1 running Win10, the other running Win7. I didn't have to do anything special on those PCs.

    Must agree with you. It works for me on Windows Insider and on RTM Windows 10 with clean install.

    Try first with some of the WDs tools. I will come back on the (my) afternoon.

    Just means that the Tables are screwed up and need flushed. Unplug the router and make sure that it flushes the tables, along with reset the Winsock on the machines.

    Names are great when a device may have a DHCP vs. Static IP. If the device has a static IP. Use that, vs the name.

    Western Digital does some screwball stuff with their version of Samba for the embedded Linux they use.

  13. Can't access NAS by name

    Ha! That did it. Maybe because the reinstall of Widows changed the "Computer Name" associated with the PC? For whatever reason, it worked.
    I could give the NAS drive a static address, but I'd rather refer to it by name. Windows gives an irritating warning popup (saying things from the internet can't be trusted) when executing a program from a NAS drive accessed by IP addr rather than name. Since save all installation files for installed software on my NAS so I get that warning a lot when the drive is accessed by addr.

    Internet Explorer and edge will do that, along with a Firewall.

    I have those devices that need to be set as a static, like my printer, NAS, Access Points, because I use the IP's in the shortcuts for them.
