If this is ongoing, try running check_dns from the command line, adding a -v (verbose) flag to see what command is being sent to nslookup and what the nslookup output is. It'll pro bably provide a clue to the real problem. -- Marc p.s. Please start a new thread when you have a new, unrelated question.
