Can't set WINS workgroup name
The NetBIOS name is already prefilled (and greyed) to something like MAC with a long hex string after it. Both my iMac and MacBook Air have this, however, I can set the workgroup name on my MacBook Air.
My iMac is connected to an Airport Extreme base station over ethernet. I'm trying to set the workgroup for the ethernet connection.
Any idea why I can't set a workgroup name?
Thanks!
