Question

Windows 2000 DNS

Asked by: tadduci

Hello,

I have two NT servers:
exchange server v5.5 on nt4 192.1.1.12
nt 4 pdc on nt 2000 192.1.1.13

My pdc does DNS and I need to be able to have internal clients resolve mail.company.com internally. On the outside of the company this mail.company.com is a valid mx record and works properly. However, when I have internal clients point at 192.1.1.13 for primary dns it has problems doing resolution for mail.company.com

Can you walk me through how to add a mx record in nt 2000 dns so that I can have mail.company.com resolve to 192.1.1.13?

thanks
tony

Have you added a zone for company.com?

 

by: tadduciPosted on 2003-01-02 at 11:51:37ID: 7657609

yes, i have a reverse lookup and a forward lookup
what should i put in these fields:

host or domain
mail server
priority: 10 i think.

 

by: geoffrynPosted on 2003-01-02 at 11:55:16ID: 7657634

You need to have two things.  One, an A record for the host  192.1.1.13.  And two, a MX record for the domain COMPANY.COM that points at the A record for the host.

i created an A record for the exhcange server
alias name of: mail
and the fully qualified name is machinename.company.com

will the alias borrow the suffix of the domain name (i.e. mail.company.com?

Any member of the zone will have the suffix applied automatically.

You don't need the CNAME entry for mail. Why don't you just use another A record for MAIL that points at the correct IP?

 

by: tadduciPosted on 2003-01-02 at 13:36:47ID: 7658320

so if i delete the cname record then create an A record for mail it will resolve to 192.1.1.12 which is mail.company.com?

 

by: geoffrynPosted on 2003-01-02 at 14:07:06ID: 7658530

right.  You create an A record for MAIL at 192.1.1.12 and then create another MX record for company.com that points to mail.company.com.  Then if you do an "nslookup", "set type=a", "company.com", it should spit out the names and addresses of both mail and the exchange box, which are the same.

 

by: tadduciPosted on 2003-01-02 at 14:14:17ID: 7658576

when i go to create a new A record windows 2000 dns calls it CNAME... ideas?

 

by: geoffrynPosted on 2003-01-02 at 14:21:57ID: 7658609

You mean if you choose new HOST record, it changes it to CNAME?

 

by: tadduciPosted on 2003-01-02 at 14:27:54ID: 7658647

yes...

 

by: geoffrynPosted on 2003-01-02 at 14:45:20ID: 7658763

It should add as a HOST record.  Are there any event log errors about adding the entry?

 

by: globetrotterPosted on 2003-01-02 at 16:21:00ID: 7659269

If the DNS Server insists to add the Host entry as CNAME it must already have the actual Host entry in it's database,
llexchbdc1                     A     10   192.1.1.12
although the output you posted doesn't show it.

I think there shouldn't be any problem using "mail" as a CNAME record unless the server is still SP2. SP3 fixed some problems with CNAME Aliases:

im a little curious as to why your internal clients are needing DNS at all for this ?

why are your clients requiring DNS at all ? Exchange clients use RPC calls and do not do a DNS lookup for the mail records for exchange.

Are you using pop3 clients on your internal network ? if so my next question would be why ?

if not what exactly are you trying to achieve with an internal mx record ? your clients should be able to resolve the mx record using normal DNS from whereever delegated DNS server is ?

or maybe i missed something in your Q ?

 

by: tadduciPosted on 2003-01-03 at 07:09:36ID: 7662420

i have internal clients that need to be able to send mail to an internal smtp system... for example mac os 10 doesnt use exchange server rpc calls, it only has support for pop3 and smtp...

the bottom line is i need the alias mail.londonlitho.com internally to work and resolve to 192.1.1.12

outlook on the pc's works fine and those clients are all using the exchange server service... no issues there...

the reason i dont use the ip of the mail server for the smtp entry is because when those people step outside of the company they use the same email client profile and that smtp ip address is not a public one (not for our use at least) I also dont want them to have a inside and outside profile, i just want one profile.

thanks.

 

by: globetrotterPosted on 2003-01-04 at 02:21:21ID: 7667502

Hi tadduci,
I think all you need to do is ensure that you have a correct Host A record for your mail server which should look like
llexchbdc1                     A     10   192.1.1.12
then the MX record
llexchbdc1                     MX     10   192.1.1.12
as well as the ALIAS
mail                        CNAME  llexchbdc1.company.com

that should ensure that mail.company.com resolves to 192.1.1.12

you cannot have a Host A record for 192.1.1.12 with the name "mail" since the machine's name is llexchbdc1. "mail" should be listed as CNAME.

If you do have those 3 entries and still have problems you might be running into a known issue with CNAMEs. I finally found the article I had been looking for regarding the SP3 Fix for a known Problem with CNAMEs
