NT_STATUS_UNSUCCESSFUL error when browsing machines/shares in Ubuntu Linux

Here’s a workaround if you encounter this error when using smbtree or using the network browser in Nautilus:

  1. First edit the Samba config file:
vi /etc/samba/smb.conf
  1. Then, find the line name resolve order = lmhosts host wins bcast and change to name resolve order = lmhosts wins bcast host

You may need to reboot in order for Nautilus to pick up the change.
