How to connect to an smb share?

You should be seeing the share in the Network neighborhood and be able to use it from there. Just open Windows Explorer and click on Network.

If you cannot see it, then you have a connectivity problem with the sharing computer.

1. Open Windows Explorer.
2. In the path bar, write \\a.b.c.d (pay attention to the backward slashes).
3. That should create a new entry in "Network" and show its content.
4. Double-click on the share you want, for instance sharename in the example of the question.
