Having a weird DNS issue. I've had a split-horizon system on my 10.6 OS X Server setup for sometime; this server runs Open Directory and hosts our website. But recently, seemingly after the 10.6.8 update, many machines are unable to view the companyname.net website from within the LAN. It sees to only be 10.7 and iOS devices, as our lone 10.6 machine works.
I can't ping companyname.net from the affected machines, but I can ping www.companyname.net. If I manually enter the IP address into my /etc/hosts file, I can view the site properly. Tried many cache refreshes, HUP clears, etc, but for whatever reason, it seems that my machines are just not picking up the DNS information about the raw companyname.net URL. Quite flummoxed!
Here's my zone file.
$TTL 10800 companyname.net. IN SOA macpro.companyname.net. admin.companyname.net. ( 2011090923 ;Serial 86400 ;Refresh 3600 ;Retry 604800 ;Expire 345600 ;Negative caching TTL ) companyname.net. IN NS macpro.companyname.net. lion IN A 10.0.1.3 macpro IN A 10.0.1.2 companyname.net.
