Okay, I created two subdomains the other day, NS1 and NS2. I could ping them yesterday, but now things are getting nutty. Here's what my DNS zone template page shows for the entries <domain>. NS ns.<domain>. <domain>. NS ns1.<domain>. <domain>. NS ns2.<domain>. ns.<domain>. A <ip> ns1.<domain>. A <ip> ns2.<domain>. A <ip> During the course of compiling this message, I have been logged into the server via SSH. When I started this message, I could ping NS1, but not NS2. Now I can' t ping NS1 or NS2. Oddly enough, network-tools.com can still ping NS1, but not NS2. Add to the confusion? Sure. webmail.<domain> wasn't working earlier. I ran the updater for horde, and gracefully restarted apache, and it started working again. Yes, I've rebooted the server, ran apachectl restart, and service httpd restart several times each. What could it be?
