Not knowing what SMB was I had to look it up. For the rest of you in question;
The Server Message Block Protocol (SMB protocol) is a client-server communication protocol used for sharing access to files, printers, serial ports and other resources on a network. It can also carry transaction protocols for interprocess communication.
In the meantime I have a few questions that may help us get to an answer;
Is this something you used to be able to do or have done before?
Since there are a range of things that SMB is used for, which one or ones are you interested in?
What device do you have?
