New SBS server intall ...

[AnthonyCasta]

Hello All! ..

We have decided to migrate from Server2000 to SBS2003, in the process I have had a few problems! I think the issues are all related, but maybe not ..

1st. I am unable to receive e-mail from the outside, I'm able to send external but not recieve, I can send and receive internal.

2nd. From an outside computer I am unable to access the website by just typing in the address ... i.e. (microsoft.com) ... However, if I type

http://www.microsoft.com

I am able to get in ..

Could these be related ... I have already checked my mx record and I am pretty sure that it is ok ..

Thx in advance ..

Does your new SBS box have the same internal IP as the old server?

If not you need to point port 25 on your firewall at the new internal ip

Are you hosting a website on your SBS box for some reason, or are you trying to access OWA/RWW ?

Actually .. It is now a new internal ip, and I have updated the MX record to read:

Name: @
Content: servername.domain.com
Priorty: 10
TTL: 1 Day

Is that correct?

Now, when I try to send to a message to my company email address from yahoo I am getting back the message that says:

Sorry, I couldn't find a mail exchanger or IP address. (#5.4.4)

HELP!!!

Check at

http://www.mxtoolbox.com/index.aspx

to see what the world sees as your hostname and external IP.

If the external IP is correct, your router/firewall needs to forward port 25 through to your SBS box's internal IP

This is the part I'm having trouble with ...

when I enter my domain name the results come back with:

Preference: 10
Host name: ana-server1.anacoreinc.com
IP Address: 0.0.0.0
TTL: 86400

I have double checked my A records:

Name: @ Content: 71.143.xxx.xxx
Name:

http://www Contact:

71.143.xxx.xxx

Are you changing stuff in your own internal DNS? You shouldn't be.

You need to contact whoever holds your mail records and get them to create an MX record that points to your server's external IP. When they have done that, the mail should start arriving (assuming the router/firewall is pointing to your SBS box). The 0.0.0.0 above is clearly incorrect and needs correcting, presumably to your 71.143.11x.x

When it does, contact your ISP and get them to set up a reverse DNS record for you. And also you will need to sort out a SPF record.

So basically I need to contact my domain name company (omnis) and have them correct the error ... I called them this morning and they told me that there is nothing that they can change? ..

I shouldn't have to change anything on my DNS server ... correct?

 

[noveyron]

No, leave DNS on your SBS box alone, you don't need to go anywhere near it. You need to contact whoever holds your mail records.

How did you go about migrating to SBS, what did you have before migrating?

 

[AnthonyCasta]

I was on Windows 2000 Advanced Server.

What I did, was start with a new server, installed SBS w/o the other servers on the network, so they are actually my backup plan! .. The only thing that was different in the install was that recommended it name my domain.local ...

Here's the funny thing .. When I revert back to my old server running 2k the IP Address shows up on the MXToolbox site. and email flows in to my old exchange 2000 server ..

Any thoughts ...

Are both of your servers using the same internal IP address? I can tell that they have different external IP addresses, and if you have both external IPs bound to the same firewall, only one of those IPs can "own" port 25.

If your servers are both behind a firewall, your firewall is configured to have port 25 traffic go to one of you internal IP addresses. Obviously it's the same IP that your Exchange 2000 server uses. When you take that system offline and put your SBS 2003 box online (how are you doing that, you didn't say), it doesn't get mail and can't be contacted from the outside, so it must not have the same internal IP as your other server.

Here are your two mail servers:
50 ana-border.anacoreinc.com. [TTL=86400] IP=71.143.116.196 [TTL=86400] [US]

10 ana-server1.anacoreinc.com. [TTL=86400] IP=71.143.116.194 [TTL=86400] [US]

The first one is listening, but the second one is not. So port 25 traffic must not be getting to it, since it should be attentive to port 25 traffic by default.

If we knew more about how you are handling your two IPs and whether both servers are behind the same firewall, that would clarify some things.
