How to fix windows 11 error code 0x80070043

Question

My Acer Aspire TC-1770 PC, Factory Windows 10 Home, windows update updated to Windows 11 Home. CPU Intel Core i5-13400, 8GB RAM.

Have a Synology DS211 that has been connected to the PC and has been visible and accessible as "Jacks Files (\DiskStation) (Z:)" in Windows Explorer when the PC ran on Windows 10 and until recently was visible and accessible since the upgrade to Windows 11.

There have been a couple of updates upon shut down in the past few weeks. I am unsure at exactly what point, but upon startup a week ago the DiskStation was no longer visible or accessible.

I have a backup PC I built that runs on Windows 11 Pro I named SAMA. Both the Acer and the SAMA PCs have been connected to the Synology DS 211 through a NetGear Prosafe FS105 Fast Ethernet Switch. The SAMA PC has continued to maintain the connection to the Synology.

I have tried Mapping the Synology got the error 0x80070043, the network name cannot be found message as follows:

I researched online how to fix this error 0x80070043 problem and tried all the YouTube solutions that appeared to no avail. I have run the ethernet cable directly from the Acer PC to the Synology in case the ethernet switch was a problem but got the exact same error message. I have tried the same map to network also checking the Connect using different credentials and got a popup screen asking for the Synology username and password. Upon providing both I still got the same error message.

From my internet searches this appears to be a common problem but so far, none of the offered solutions work. I am considering purchasing Windows 11 Pro to see if that solves the problem.

Any suggestions are appreciated.

Hi J Bowen,

Thanks for your post. Please type the same path in the file explorer and see if you can access the folder . If so, right click the network and map the drive directly. If not, ensure that you have sufficient access for SMB file transfers (this requires NetBIOS ports open because SMBs use the NetBIOS protocol to transfer data).

You might also check to see if the Vista workstation has a gigabit card. If so, check for the following local policy.

Enable the Always wait for the network at computer startup and logon local policy. To do this, follow these steps:

1. Start the Group Policy Object Editor (gpedit.msc).
2. Expand Local Computer Policy\Computer Configuration\Administrative Templates\System\logon.
3. In the results pane, right-click Always wait for the network at computer startup and logon, and then click Properties.
4. On the Setting tab, click Enabled, and then click OK.
5. Restart the workstation.

Best Regards,

Ian Xue
