Should my AEBS show up under "Shared" devices?

Here's a weird thing...

I just set up a brand new AEBS last night (upgraded form an Express), and I notice something under "Shared Devices" that appears to be my Base Station (though Finder is reporting it as a Windows PC).

Here's how my Base Station is set up:


And here it is in Finder:


Granted, the case and format is a bit different ("Rec Room" vs. "rec-room"), so cold this be a nearby computer? There shouldn't be anyone else on my network... I created a WPA network with a really strong password, so I can't imagine it's a neighbour's computer.

If I try to connect to this device, it just fails (almost immediately).

This doesn't seem right to me... what's going on?

I have no AirDisk mounted (and haven't). I have that port plugged into a printer, but even that's not on.

I guess if it's an issue, then logic may not apply.

Thanks.
