Tobias,<br><br>So you experienced the same thing? A failure when a CNAME resolves to a host on another authoritative nameserver? Were you using nslookup for your testing?<br><br>Thanks,<br>Tom<br><br><div><span class="gmail_quote">

<p>Yes, when it starts in the monitor mode it connects to the mysql
server. Also, I can resolve any of my A records, just not the CNAME
record which is formatted as I provided earlier.<br><br>
