Gen 1 ATV appears in workgroup "AppleTV"

The G1 apple TV on a wiindows network appears in a workgroup called APPLETV when browsing from a windows computer.


I want to change this to something more appropriate. I found



    preferred master = no
    local master = no
    domain master = no
    client lanman auth = yes
    lanman auth = yes
    name resolve order = bcast host
    workgroup = WORKGROUP



As you can see it says workgroup name is workgroup, but it does not seem to apply. Is being overridden elsewhere?
