OSX - deleting shared connected servers under finder/network connections

I've digged around for a while and cannot find a resolution:

I am curious if anyone has ever figured out how to remove "once" connected servers, from the list.

I attached an image as an example. I've tried drag and drop to trash and it says "The item cannot be moved to trash because it can't be deleted".

Even trying to "eject" doesn't do anything, nor does a reboot help, or restarting finder.

What gives? It's not really causing issue- it's just annoying.

I attached a photo to give anyone a better idea of what I am referring to.

The current one that I use is the 10.0.1.150 address shown in the picture.

It's the two "iRaid" and "iRaid-Backup" connections I cannot remove for some reason.

Any help would be great - thanks a ton.
