Mounting smb shares after upgrade to Catalina not working

I have a NAS storage device connected to my router on my internal network which is protected by a username & password. Prior to the upgrade to Catalina my 2016 15" Macbook Pro had no issues connecting to these shares using smb://routername/share. After the upgrade to catalina I can no longer connect to the network shares. It keeps asking me for my username & password, and no matter what I enter the dialog box keeps coming back. When I try on the command line using "mount_smbfs //username:password@routername/share mountpoint" I keep getting the error message "mount_smbfs: server rejected the connection: Authentication error". If I go into the router and remove the credentials from the shares, then the mount works fine. I know the credentials are correct (I reset them in the router).

I've also re-enabled NetBIOS as described in this article (https://medium.com/@gobinathm/how-to-access-smb-printer-shares-in-macos-catalina-10-15-17ea91d2c10b) but that did not help.

Very helpful! Thank you! I also have a couple of WDSHARESPACE NAS devices. I went into each NAS device and saw that AFP was enabled. Then I went to 'Go', from the MacOS Finder menu bar, selected 'Connect to Server', and entered in the string that you listed in your reply below. I entered the username and password, and it worked perfectly!

The link at the bottom was also a good overview of AFP, SMB, etc. that provide some simple explanation.

afp://username@<NAS ip address>/sharefoldername

This doesn't work for me. When I put in my username/password it keeps telling me my username & password isn't correct, which I know it is, since I just set it on the NAS. The only way I can connect is to turn off authentication on the shares.

That solution works great if you have the ability to control the protocol version on the NAS side. In my case my drive is plugged directly into my router and my router offers no user configuration of the protocol being used.

This just shows the contempt that OS X developers hold for the user community that something as fundamental as SMB does not function properly. I accept that older SMB protocols may not be as secure but even Microsoft allowed there server configurations to be modified so that older SMB shares could still participate on the network until such time as they could be replaced.

There are millions of users out there who's NAS servers are telling them that AFP has been depreciated by Apple and replaced by SMB which doesn't work come on apple get yourself into gear and sort this problem out.

IT! is terrible when you can't do updates to your system even security update to keep your system safe for fear that your system will be broken.

Can’t agree more Vista was Microsoft’s vision of how things should be without thought of consequences to the use community and now Apple are following in the same vein. Maybe they will learn from this where Microsoft didn’t (Windows 8). As an Apple user but a Windows system architect I had to watch some of my cooperate clients suffer when things a just didn’t go well during upgrades or in most cases had to say no we will have to pay for extended support till the next version of windows no I’m on the receiving end. I was thankful I have a 2011 MacMini still in use so I could continue to access my SMB shares and continue to work.

Come on Apple think before you deliver your version of utopia.

Anyone have any thoughts on how to get Catalina to connect to a SMBv1 share that requires credentials?

Enabling AFP isn't an option. I have no control as to what protocol the router uses.

I'm using SMB version 3.02 and it fails.

It's not a NAS specific device. It's just an external USB drive attached to my router's USB port. All the shares are managed via the router.

Thank you for posting. My problem is the reverse though the shared drive isn't attached to a Mac.

Oct 14, 2019 9:59 AM in response to edeandrea

@edeandrea: so, there must be a router setting(s) for enabling sharing to effect the same thing I did on my Mac mini server. Good luck!

I absolutely agree, Abarth. Preserving settings is a fundamental tenet for upgrades.
