I got a Desktop Shortcut for "Network Servers" which launch a Nautilus Network window. I don't know why this shortcut appeared in the first place. However I would like to get rid of it. Right clicking on the shortcut shows that the option "Move to Trash" is greyed, highlighting a permission problem?

This option is greyed may be because I am not considered as Root (by default in Ubuntu). However I don't know where the file is and therefore can't change its permission. Can I get rid of that shortcut in a terminal ? where is the file to remove ? Can I tell Ubuntu that I am Root to allow the Move to Trash option in the context menu ?

It looks like Desktop shortcuts management is a hell in Ubuntu 11.10 ...
