Question: 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.
