Guest wilscott1st@yahoo.com Posted January 29, 2008 Posted January 29, 2008 Our company finally got a web page up and running yesterday afternoon. The company that is hosting the website went and changed the public DNS records yesterday and Whammo! No email. The URL and Domain names are the same: (http://mydomain.com VS username@mydomain.com) Doing a lookup at dnsstuff.com I can see that the MX record now points to the web-server at the company that's hosting the website. It also *looks* like the reverse lookup is pointing to our exchange server inside our domain (public ip) however, no email is getting through to us inside the domain from outside the domain. We can send mail out and to each other succesfully. My Question: Do I need to reconfigure DNS on our server to accomodate the new setup? (DNS and AD and Exchange all reside on same box, Server 2000 SP4, Exchange 2003 SP1(?)) It doesn't *seem* like I should have to reconfigure anything on my end. It seems more like the webserver people have something wrong on their end?

No. Your internal DNS has nothing to do with this - don't touch a thing. > (DNS and AD and Exchange all reside on same box, Server 2000 > SP4, Exchange 2003 SP1(?)) You ought to be on SP2, and you can check that in ESM if you right-click on the server object, but that isn't important now. > It doesn't *seem* like I should have to > reconfigure anything on my end. Correct. > It seems more like the webserver > people have something wrong on their end? Absolutely. However, as you've masked your domain name it's hard for anyone to advise you more specifically. Here's what you probably want: Two A records: domain.com (points at your webhosting IP) whatever.domain.com (points at your own public IP for mail) Your MX record should be whatever.domain.com You may also have a CNAME for www, which points at domain.com.

Things I suspected to be true were confirmed by you Lanwench, thanks for your assistance. (even the "oughta be on SP2" part, I just hate fixing things that aren't broken)

You're welcome - good luck. > (even the "oughta be on SP2" part, I just hate > fixing things that aren't broken) But service packs fix things that *are* broken as well as adding new features. The fact that you can't see the broken parts doesn't mean anything. You need to stay on top of SPs - you don't need to install them the first day they come out, but you do need to install them. E2003 SP2 is a huge deal - get it on there ASAP. Just make sure you first remove the old IMF 1.1 in add/remove programs (if you'd manually installed it). Then start using a newsreader instead of Google Groups, and subscribe to m.p.exchange.admin :-)
