Having waited 8 hours for the delivery man today, I've finally at 6pm, unpacked one of the two brand new SL iMacs and am installing it.

First tiny little glitch, it will be very obvious to everyone else, I hope.

Brand new, so I told it the owner's name (my boss) let's call him John Smith.

Network (local network in this office) shows John Smith's iMac.

Boring. Not the name we chose. Renamed the HD icon on the desktop to (what he'd chosen), Sherlock. Then went into System Prefs, Sharing, typed in Sherlock.

Now, other Macs on this local office network are showing both

John Smith's iMac
and
Sherlock.

(to pre-empt the next question, yes I did counsel against "Sherlock" as a network name because it's already a Mac application.......)

So how do I get rid of John Smith's iMac on the Finder>Network display on the other iMacs here, please?

I'm sure it's something really simple. Thank you in advance.

(goes back to installing software..........)
(will probably have other SL questions too.......)

Thanks again <wrings hands and smiles>
