I have the samba daemon running on my server, and have successfully connected to it from the Ubuntu machines in my schools computer lab. However, when I try to connect to it from either my Windows or Ubuntu box at home, I am unsuccessful. In the case of Ubuntu, I receive the error "NT_STATUS_UNSUCCESSFUL". My googling hasn't turned up any relevant solutions, and I'm not really sure how to go about dealing with this.
The command I am running is:
smbclient -U <My username> //<My server's IP>/<the share name>
