RPC error: cannot connect to NAS drive

Since upgrading from Win7(64) to Win10(64), I have been unable to connect to my NAS drive (\\NET_DRIVE). While I can see the drive in windows for mapping a drive, File Explorer and Network Sharing, when I try to map the drive, I get the following error:
\\NET_DRIVE is not accessible.... A remote procedure call (RPC) protocol error occurred.

• The NAS drive is connected to my WiFi router, not to a remote computer.
• The user profile I'm using has administrative rights
• This problem did not occur when running Windows 7. It started when I upgraded to Windows 10

How can I fix this so I can access my NAS drive?

Unable to map NAS drive

I have a NAS drive (WD My Cloud Mirror) that was originally set up and mapped to an older laptop of mine. I have not used this NAS drive in a while. I recently dusted off the drive and tried to connect it to my new laptop when I ran into difficulties.

The NAS drive is directly connected via ethernet cable to my laptop.

Laptop is running Windows 10 Enterprise 1809.

Laptop's IP address on the ethernet card is set to 192.168.1.1

I was able to retrieve the IP address of the WD NAS drive by using the arp command and it's set to 192.168.1.2

I have forgotten the name of the root share folder on the NAS drive.

The problem:

I am unable to map the NAS drive to my laptop. When I try to click on Network in Windows Explorer OR use the Map Network Drive option, I get a "Network Discovery is turned off" error.

To enable Network Discovery, I turned on / enabled all of the below

1. In Advanced Network Sharing, network discovery is turned on for Private, Public, Domain and All Networks

2. DNS Client, Function Discovery Resource Publication, SSDP Discovery, and UPnP Device Host sevices are running

3. Network Discovery is checked in Windows Defender

4. Ran the following command as administrator netsh advfirewall firewall set rule group=”Network Discovery” new enable=Yes

In spite of this I get the "Network Discovery is turned off' error.

I am able to ping 192.168.1.2 in the command prompt and get a response.

Any suggestions on how to fix the error OR another way to access the NAS drive would be highly appreciated.

Thanks,

Adi.
