Intel Mac :: Add Network Icon Onto Dock

We have an issue with adding a network icon to the dock. Some machines display it fine and others don't. 

I remember him telling me that using workgroup manager doesn't work so he used to do it another way using a plist file or something along those lines. I've found the file he means but it's a .app file which contains a unix exe? 

I've googled this problem and there seems to be people doing this with profile manager but we don't have this software. I assumed this could be done with workgroup manager but for some reason it doesn't. 

The shortcut needs to simply go to \servernameshare 

The other complication i'm going to have is that the \servernameshare is being moved to a different location as it's grown so big we have run out of space. The shortcut will need to be edited with the new sharename.
