nslookup and internal server

I recently switched a domain from one web server to another web
server.

I received complains that people of a company cannot send email to
this
domain. After musch hassle I discovered later that the company
maintains its own server.

By typing 'nslookup' at command prompt, the default DNS server points
to its windows server.

I guess that its windows server has not updated its DNS record even
after more than a week. Am I correct on this ?

Should the IT department of the company do something to update its DNS
record.

I could be widely off mark. Do elaborate. Thanks.

I had to read this through a few times before I understood what you were
trying to say with the limited configuration data you've provided that we
normally need to diagnose an issue, such as previous IP, new IP, who was
your previous hosting provider, your new provider, was public DNS server
registrar records changed, etc.

So just to get it straight, you had a website running on a Windows server in
your company running your network. Then you decided to move the website (not
move the domain) to a different Windows server (or is it hosting company?),
which is not part of your company, that is at a different location entirely.

Correct so far?

Now the server would of course be using that other company's resources, such
as their network and their DNS server. Now you are wondering why it's host
record is not updating into their DNS server.

But then again, if it is just a web hosting company, and you did notn change
DNS info, then the public DNS records for your domain (assuming this is a
public website), have to be changed manually with whomever your registrar
is.

If mail delivery is now hampered, then it may tell me that you moved to a
different hosting company, including your Hostname Server (SOA or DNS)
records to that new company.. If so, have you asked them to change your MX
record to reflect the new mail server, or make an entry for your MX record
to point to the existing

If I misunderstood anything, please elaborate wtih the following info to
better understand the before and after of what occured.

Can you post the results of your nslookup and explain what was being looked
up?

Thanks,

My apology Ace Fekay.

Originally the domain (take it as abcd.com, pages at http://www.abcd.com),
is at a hosting company A.

I create a domain (abcd.com) on another hosting company B; change the
DNS record to point to the server at B (the domain space is removed at
company A).

The hosting package is irrelevant, I think (but it is on Linux).

After 72 hours (that is what commonly said) of DNS record propagation,
everybody will be directed to the server at B. The change will be
transparent to others, I think.

I can send email to 'abcd.com' ( I am using another hosting company).
I have done this several times before.

But this time one company says it cannot send mail to 'abcd.com', and
this company maintains its windows server, I was told (see below the
default server, private IP).

Following is the nslookup log (name fictitious); the Non-authoritative
answer is not correct.

C:\WINDOWS\system32>nslookup
Default Server: tim.atec.nitako.local
Address: 10.174.10.2

> server 202.188.0.132

Default Server: cns1.tm.net.my
Address: 202.188.0.132

> srihangdo.com

Server: cns1.tm.net.my
Address: 202.188.0.132

Non-authoritative answer:
Name: srihangdo.com.tim.atec.nitako.local
Address: 203.106.203.238

Without the actual domain name to test it from my end as an "outsider," it
is difficult to help or provide a specific diagnosis other than suggesting
to check the MX record. I assume the only thing you've changed on the
srihangdo.com is the www record. Was the MX record changed? The MX record is
what other mail servers in the world use to find the mail server of your
srihangdo.com domain. If that was changed, then I can see why you are not
receiving mail.

If I can send email from, say '(E-Mail Removed)' to '(E-Mail Removed)', can
I assume that the MX record for the domain 'abcd.com' is correct ?

Thanks and regards.

Possibly. I say possibly due to the time it takes to propagate a change.

I am not sure is this is your domain name or not, but I checked net.my and
tm.net.my for MX records. The following below is what I found. If this is
correct, adn the other company still can't send mail to tm.net.my, then it's
either something on their end blocking it, or something on your end not
allowing to receive mail from them. The only way to better ascertain this
issue is to ask them what type of SMTP error message they are getting when
trying to send mail. The SMTP error message will help point us in the right
direction to diagnose the problem.

Non-authoritative answer:
tm.net.my MX preference = 10, mail exchanger = mx.tm.net.my
tm.net.my text =

"v=spf1 ip4:202.188.0.128/25 ip4:202.188.1.1/27 a:service.tm.net.my
a:we
b-smtp.tm.net.my a:smtp2.tm.net.my a:smtp.tm.net.my a:service2.tm.net.my
a:edm.t
m.net.my a:edmtrace.tm.net.my a:smtp-proxy.tm.net.my ap-smtp.tm.net.my
a:iport
1.tm.net.my -all"
tm.net.my nameserver = ns2.tm.net.my
tm.net.my nameserver = ns3.tm.net.my
tm.net.my nameserver = ns1.tm.net.my

tm.net.my nameserver = ns3.tm.net.my
tm.net.my nameserver = ns2.tm.net.my
tm.net.my nameserver = ns1.tm.net.my
mx.tm.net.my internet address = 202.188.0.213
ns2.tm.net.my internet address = 202.188.1.8
ns3.tm.net.my internet address = 202.188.0.184
ns1.tm.net.my internet address = 202.188.0.183
