At wit's end. Have MBP named newt running High Sierra. Have Windows 10 machine named "Vader" that's always up & running with a physical drive (X:) shared as //Vader/x with permissions set to Everyone having full control. Other Windows machines can access share just fine & read, write, etc. Windows 10 box has user Adams with no password & automatically logs in at boot.

Prior to installing Sierra, had no problems accessing share. Since Sierra (now on High Sierra, hoping it'd fix but didn't), I haven't been able to access at all, always with the following error with text There was a problem connecting to the server: enter image description here

Windows 10 machine's workgroup is WORKGROUP, and so is MBP's: enter image description here

Here's newt's DNS settings: enter image description here

I've got a pretty simple Google WiFi setup (with 3 units) providing my home network. All machines are on the wifi network ( Here's some terminal output from newt:

$ ping vader
PING vader.lan ( 56 data bytes
64 bytes from icmp_seq=0 ttl=128 time=2.208 ms
64 bytes from icmp_seq=1 ttl=128 time=5.940 ms

$ smbutil lookup vader
Got response from
IP address of vader:
$ smbutil status
Using IP address of

Server: VADER
$ smbutil identity -N //vader
smbutil: server connection failed: No such file or directory

Any help would be greatly appreciated. I don't know what else to try. I've searched many docs, forums, StackExchange sites, etc.

  • Have you tried connecting using the server's IP address?

  • Yes. Same result. Commented Oct 17, 2017 at 14:49
  • I have the exact same problem. Driving me crazy. It all used to work perfectly until I updated the OSX. One sliver of hope is that I can connect my PC to my MBP. This means I can be on the PC and see the files on my MBP that are shared and make file transfers. However, while on the MBP, I can't connect to the PC, even though Finder shows it under "Shared" in the sidebar. Nothing has worked. Very frustrating.

    Using Go>Connect to Server from the Finder menu was suggested to me to be the bulletproof method, but I get "The share does not exist on the server. Please check the share name, and then try again." I'm not sure how to interpret this. One thing Mac does really poorly is provide any plain language error messages. I too would really appreciate any help/ideas.

For me the solution was to check if SMB server was active on windows pc (and it was not!!, just SMB client is active by default):

  • go in search field at the right of WINDOWS icon and type: WINDOWS FEATURES
  • scroll the list and find SMB support
  • make sure that SMB server is checked, if not check it and restart pc.

  • I had the issue of being able to connect to a Mac, but not see it in the Network list. After enabling these settings, the Mac became discoverable (along with all other devices that use SMB. Printers, routers, etc.) Commented Apr 28, 2020 at 7:39

Ensure the Network Connection on your Windows 10 computer is configured to allow File and Printer Sharing:

Control Panel -> Network and Internet -> Network Connections. Right-click the Network you are using, click Properties, and ensure File and Printer Sharing for Microsoft Networks is selected.


This worked for me. Go in to sharing preferences on your mac and make sure when you click on options its set to "share files and folders using SMB" and not AFP. Scroll down and check the box next to the account and it worked instantly.enter image description here


After trying the suggestions in this post I went on to Finder > Network > Double click on the Computer > Connect As, and then I entered my windows user name password. It then showed the list of shares. Then I was able to mount one of the shared location.


I stopped being able to connect to my Windows laptop from my Mac running 10.13 after several updates to Windows 10. I did two things to get my connection working.

I turned on the SMB settings on my Windows laptop as @marsartis did. I still had problems connecting.

I noticed that in the Apple instructions for 10.14 & 10.15 it said that you needed to include a sharename in the smb server address. That was not required with earlier version of Windows 10. I used these instructions to create a sharename. I added the sharename to my smb server address and was able to log into my Windows laptop and succesfully connect.


It sound silly.... but I had a big fight with my MAC/Win10 LAN. I tried everything I read and nothing worked....till I set a password in the windows (onlyuser-account without M$-addons and logins) computer.

After restarting, the PC appeared instantly on the Mac

  • I had the same thing - tried everything but nothing worked. Managed to resolve this by adding another local user with a password. This might be easier than changing/adding a password to the main account

Had the same issue connecting from a Mac to a Windows 7 Machine. It appears that this was related to a faulty Windows update released July 10th 2018 and then further corrected in another update on July 16th 2018.

It resurfaced for me because of a failed Windows update that blocked the autoupdate process.

Download and install KB4345459 manually from Microsoft Update Catalog to fix the issue.


I was unable to connect to the user on my Windows laptop as my MacBook would keep giving an error that server not found. I finally turned off "Microsoft Account" under account settings on my windows laptop and chose to sign in with a "Local Account" instead.

This somehow worked and my MacBook finally asked me to login with the registered user credentials of my windows laptop.


Go to the  Apple menu and choose ‘System Preferences‘ from the drop down menu. To enable File Sharing in macOS or Mac OS X, open the ‘Sharing‘ pane of ‘System Preferences‘ and select the option for ‘File Sharing‘. Windows computers and Macs can then see your computer on the local network. If you want to add an existing user for SMB file sharing open ‘Options…‘ for selecting and activating the user. For details see Apple’s support document.

  • The OP clearly asked about accessing a Windows share from their Mac, not sharing something from their Mac to Windows.
