Some users have reported problems using a Windows Server using SMB. This is caused by a change that Apple made in the operating system.  To fix this, you need to force the login to use SMB1 protocols.

To force all connections to be SMB1:

  1. Open a Terminal window
  2. Paste in the following line followed by the return key (should be all on one line):

echo “[default]” >> ~/Library/Preferences/nsmb.conf; echo “smb_neg=smb1_only” >> ~/Library/Preferences/nsmb.conf

What the command does:

  1. Creates a file called nsmb.conf  in your  home directory at the path ~/Library/Preferences/nsmb.conf.
  2. Adds directives to force SMB connections to use the SMB1 protocol.

How to remove the workaround:

  1. Open a terminal window
  2. Paste in the following at the prompt and then hit the return button:

rm ~/Library/Preferences/nsmb.conf

You need to do this for each user.


This problem has been fixed in the upcoming PowerCADD 9.1.4
