How can I fix the Finder on my Apple Mac? - Menu Problem

After fiddling about with some network settings at work (active directory etc), the Finder on my Apple Mac now ALWAYS displays a "Shared" option on the left hand menu with the word "All" below it - even if I'm not connected to any network.

I'm pretty sure this never used to be like this, instead it only used to show up other computers available to connect to on a network if I was connected to a network.

If anyone knows how to fix this, that would be great. I should also mention, it's not something that can be resolved in the Finder preferences - I've tried this already. Thanks

Here's a link showing what I can see on my finder.

No matter what I do (connected to a network or not) it always displays "All" beneath "Shared". I know it's not a big deal but I don't like being defeated! Please help! Thanks.

In the task bar:

FINDER > Preferences > Sidebar > SHARED

uncheck all of the shared items. You may want to reboot.

See what happens.

Hmm no that didn't work sadly
