DNS on dedictated web server |
|
|
My company has an externally located dedicated server running Windows Server
2003 Web Edition that was previously used for web/email but is now unused. I
want to get it setup properly again to use for testing but need help with
some DNS settings.
I want to have it setup as the primary DNS server, purley for
testing/educational purposes, with secondary DNS being hosted elsewhere.
I've made an attempt at setting it up and it seems to work ok for web, but
we've had some problems sending/receiving emails from certain ISPs and I'm
told this is a result of incorrect DNS settings.
I'll list the config I've used and hopefully someone can tell me what needs
corrected:
- System Properties - Computer Name:
"Computer Name": server1
"Primary DNS suffix of this computer": mydomain.com
"Full computer name": server1.mydomain.com
- TCP/IP Properties:
"Preferred DNS Server" set to machine IP address
No "alternate dns server"
- Advanced TCP/IP Properties - DNS:
"Append primary and connection specific DNS suffixes." Selected
"Append parent suffixes of the primary DNS suffix" Checked
"DNS suffix for this connection" blank
"Register this connections address in DNS" Unchecked
- Advanced TCP/IP Properties - WINS:
"Enable LMHOSTS lookup" Unchecked
"Disable NetBIOS over TCP/IP" Selected
- SERVER1 DNS Properties - Interfaces:
Listen on "All IP addresses" selected
- SERVER1 DNS Properties - Forwarders:
DNS domain: "All other DNS domains"
Selected domain's forwarder IP address list: ISPs primary dns IP
& ISPs backup dns IP
"Number of seconds before forward queries time out" 5
"Do not use recursion for this domain" Checked
- SERVER1 DNS Properties - Advanced
All at defaults
- SERVER1 DNS Properties - Root Hints
All at defaults
- SERVER1 DNS Properties - Monitoring
Both tests pass
- Forward lookup zone for "mydomain.com" *
@ A xxx.xxx.xxx.xxx ***
ns1 A xxx.xxx.xxx.xxx
mail A xxx.xxx.xxx.xxx
server1 A xxx.xxx.xxx.xxx
ftp A xxx.xxx.xxx.xxx
www A xxx.xxx.xxx.xxx
@ NS ns1.mydomain.com
@ NS ns1.backupdns.com
@ MX mail.mydomain.com
- Forwrd lookup zone for "testdomain.com" **
@ A xxx.xxx.xxx.xxx
@ NS ns1.mydomain.com
@ NS ns1.backupdns.com
@ MX mail.mydomain.com
www CNAME testdomain.com
* mydomain.com denotes the domain used on our external dedicated server.
None of our other internal or external use this domain.
** testdomain.com denotes a domain that would be hosted by the server
*** xxx.xxx.xxx.xxx deontes the server IP address.
The only other setting I think is relevant is the reverse DNS for the
machine IP which is server12345.isp.com and not server1.mydomain.com
Apologies for the long post, as I've said the problem is sending/receiving
mail from some ISPs which I have been told is the result of a DNS config
problem.
If anyone can see any mistakes or recommend improvements I can make to the
setup I would be most grateful. If any more information is required then let
me know.

Thanks for your reply. The reverse DNS is set by our ISP, so I've asked them
to change it. Do I also need to add a reverse DNS record for the machine IP
on our server?

What does reverse DNS have to do with sending emails?
Email is moved by the MX records. MX records points the email the receiving
email server.
If I have domain123.com and my website is www.domain123.com its IP address
could be 1.2.3.10 could have my reverse setup to be that 1.2.3.10 is
www.domain123.com but this has nothing to do with EMAIL.... As my email
server could be at wehostyouremail.server.com I would just state that my MX
for my domain (domain123.com) is pointing to wehostyouremail.server.com. As
long as wehostyoursemail.server.com resolves and accepts my email there isn't
any issues.
I can even move on and make sure I have SPF TXT records defined that state
that wehostyour.server.com is my only email server and this would help
prevent users from using my domain123.com domain to send fraudulent email.
