We had been having some problems w/ dns for OS 10.4 users. After running lookupd -flushcache didn’t work, and host was returning the correct values I got confused. Google to the rescue once again. I fixed it with scutil. If I came from BSD maybe I would have already known about it. Another item of interest is dscl. Ryan says: as of 10.5 netinfo is no longer in use. Instead I have to use “local directory”. I should also install the server admin tools.
