Go into the management GUI.  Click SERVER MANAGEMENT at the top.  On the
left side - click SYSTEM SETTINGS and TCP/IP.  The second window down is
where you list the DNS servers for your BX server to use.  

This is not the area for the domains on your box, but the DNS servers your
server uses (like your ISP's DNS servers, or the ones in the NOC where your
server is located). 

If those DNS servers are not set - the most common symptom is a long wait to
log in via SSH or FTP.  Its a timeout while the server attempts to do a
reverse lookup and get a name for the logs (instead of just the IP).  But
once in - switching user doesn't occur any delay. 

One thing to remember - if the system you use to SSH from is listed in one
of your own DNS server's domains, you'll suffer that delay whenever your own
DNS servers are down. 

Fix that DNS resolution problem, and your delay will go away. 

As soon as I fixed the DNS issue, the delay did go away, the authentication
now is instant.  I still don't know though why when I add a CNAME record to
a particular domain, it is bringing down the DNS

The CNAME record I'm adding is like this. schedule.domain.com alias to
schedule.someotherdomain.com

As soon as I save that record, it kills BIND.

When I look at the  messages log file it says that there is an error in the
configuration, and what I can see from the log files, it loads up all the
domain names, but when it comes to that one it has something like _default
domain.com etc .  I think the _default tag is what causing bind to not load
up, but I don't know why a simple alias could do that.

Thanks for all the help :)
