SMB sharing not working after windows 10 update Build 2004 update

I use a Drobo5n NAS and prior to this update, had no issues with connecting mapped drives.

Once I did this update however, I found that it no longer accepted the mapped drives on many computers - some immediately - and a few several days later (after working initially). 

I have had to turn on SMB1 Client for other software/hardware connections so I first verified that it was indeed set up but that alone was not the answer.

For some computers it was just a matter of running command prompt as Administrator and using the following for each drive I needed to map:  

@echo create new drive mapping for P:

@net use P: \Drobo5n\Public /persistent:yes

This did work on 1 PC.

But on another, I had to add the following: 

from regedit:

HKLM>SOFTWARE>Microsoft>Windows>CurrentVersion>Policies>System 

add Dword(32Bit):  EnableLinkedConnections 

change Value Data to 1 (Hexadecimal)

Save

For another PC, after doing the above steps I had luck after doing an additional command:

Shut down all computer and network gear and restart pc

Press Windows Key + R

Type: services.msc, hit enter

• Start the "Function Discovery Provider Host" and "Function Discovery Resource Publication services and set to Automatic (delayed start)

-Open Explorer Network, enable network discovery if prompted

and....

run gpedit.msc

computer configuration\Administrative Templates\Network\LanmanWorkstation   

ENABLE insecure guest logon.

I had 1 computer that I used every fix found and the above mentioned as well as all the "fixes" located at TheGeekPage.com/Fix-windows-10-error-code-0x80070035-the-network-path-was-not-found and still no connecting.   

I was able to reconnect to the one PC that had a mapped drive that no longer worked by adding "  .\  " in front of the username (I had to use the user name of the PC) and their password.  I had previously been able to access it with the username (of that pc) alone, but no longer.

The Drobo5n Dashboard won't mount the shares either... (I can ping and get replies back from the device)

I now get an error about the server cannot perform the action requested.  I tried to find articles about that message but most were written in 2012 or 2015 - not current.  I tried a couple without success.

I finally took the PC back to the previous version and like a charm, everything works great.  I turned off the automatic updates so it won't install this update without my knowledge/permission and have turned it off on the other pc's i manage.

There is no server at this office; we use rdp to access a cloud server for our EMR.  I have spent approximately 10 hours on 3 pc's alone just to get them up and running.

I had a similar problem after installing windows 10 version 1809 I was no longer able to access my NAS.

After enabling SMB 1.0 manually as suggested by several forums I was able to se the NAS in the Network, but was still not able to connect getting an error message.

At the end after trying all different kind of solutions at what worked for me was adding the credentials to access the shared folder manually under Control Panel/Credential Manager  Windows Credentials  Add a windows credential. Providing the network address as: \My_NAS_name\My_Shared_folder_name  together with user name and password.

Once the credential was created I was able to access the NAS directly from Network in File Explorer.

Hope this helps

Yep, windows is totally garbage when comes to Network sharing stuff for normal user (e.g my parents) so normal users have to use USB Thumb to transfer 2mb files between computers in my house xD

Anyway I had same issue, it solved my problem: 

• Control Panel > Program & Features > Turn Windows features on or off > look for SMB 1.0/CIFS Sharing support and enable it.
• Whitelist for SMB https://helpdeskgeek.com/networking/cannot-see-other-computers-on-network-in-my-network-places/Then I could no access to network location (error 0x80070035),

but this fix issue: https://www.youtube.com/watch?v=2ZkFptCwb1A
