Internal to external DNS issues

Hi everyone, I'm trying to get my head around this issue - I would like to be able to put "http://domain.com" into a web browser and have it resolve to "http://www.domain.com" but currently it does not INSIDE my network... outside my network it does. Internally my servers host mail.domain.com and helpdesk.domain.com, but we use an external web host for www.domain.com Here's my domain.com.zone file: $TTL 14400 domain.com. IN SOA password.domain.com. postmaster.domain.com. ( 2007112027 ; serial 3h ; refresh 1h ; retry 1w ; expiry 1h ) ; minimum domain.com. IN NS password.domain.com. domain.com. IN NS password2.domain.com. domain.com. IN NS ca1.ny.towerstream.com. domain.com. IN NS ca2.ny.towerstream.com. domain.com. IN A 10.0.1.11 password IN A 10.0.1.11 ldap IN CNAME password powerschool IN A 10.0.1.6 password2 IN A 10.0.1.12 ms IN A 10.0.1.14 hs IN A 10.0.1.15 library IN A 10.0.1.2 helpdesk IN A 10.0.1.101 es IN A 10.0.1.13 www IN A xxx.xxx.xxx.xxx mail IN A 10.0.1.111 domain.com. IN MX 0 mail retrospect IN A 10.0.1.200 On suggestions from users at the Apple discussion forums, I tried modifying line 11 (domain.com IN A 10.0.1.11) to say domain.com. IN CNAME www.domain.com. but when I made that change, I could no longer reach my INTERNALLY hosted "mail.domain.com" and "helpdesk.domain.com" sites. Does anyone have any suggestions for things I might try here? I would really appreciate the help Running 10.4.10 on this server (though I don't know if that matters much for DNS), the box is also running DHCP and is OD Master for my network (using network home directories, homes on three separate servers). thx Blair
