I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

This will affect a lot everything..  You will need to make sure you have a DNS alias setup to still have the old name resolve as well.  If not, once you rename the box, Exchange will STOP working.  Everything is done by FQDN.  You will also need to update the SSL certificate as well.  Also check your configurations:  owa, ecw, active sync, etc...they all probably have hard coded url's listed.

It can be done, but i would highly recommend not changing the name of the server once Exchange is installed.  you might be better off standing up a new server and migrating all the mailboxes,public folders the new server.  I have seen changing the name muck up Active Directory as well.

Agree 100% with above.  Also, if you change the server name you will be running in an unsupported Exchange configuration.

You would be better standing up a new Exchange server and migrating everyone to that then decommission the old server.

This falls under the category "Things You Should NEVER Do".

Creating Active Directory Users from a Text File

If your organization has a need to mass-create AD user accounts, watch this video to see how its done without the need for scripting or other unnecessary complexities.

Scott CSenior EngineerCommented:
So you've already renamed it?  From the way your question reads you had not renamed it yet.

If you've already done this then you are in a world of hurt.  

You can try renaming it back and see if things start working.  I don't know if that will make things worse or not.

I honestly don't have any other advice.  When I worked at MS as an Exchange Engineer this was something that was never done because it would mess up so many things.

Actually I was smart enough to write in Experts . . BEFORE :)

So here is what seems like I need to do:
I need to rename my exchange to
because that is what is the certificate secures and that seems to work best.
I am randomly able to send :: recieve emails

I don't know what to do. Sometimes it works ... sometimes it does not
Chad FranksSenior System EngineerCommented:
if you renamed it already, you may have to start from scratch, did you backup your exchange server before all this?
Starquest321Author Commented:
Let me explain: My question was an intention. I have not done anything.

I have an exchange box . . with
I secured a certificate on

That seems to be creating issues. I am not able to send receive emails. Sometimes I am. I am thinking it's a DNS issue.

Can someone advice?
Will SzymkowskiSenior Solution ArchitectCommented:
A certificate mismatch will NOT stop mail flow to the internet. If you can receive but not send then you need to check the following...
- Send Connector Configuration
- Firewall NAT'ing to/from Exchange Server

Please please help .... 4 days I am on this issue. Maybe the DNS is not proper.
Will SzymkowskiSenior Solution ArchitectCommented:
You also need to reference your logs. have you checked the Queue Viewer to see if there are any messages stuck in the Outgoing Queue? If there are it should also reference an Error message as well.

- Send Connector Configuration
- Firewall NAT'ing to/from Exchange Server

Can you please expand? What do I need to check? Should I screen screen shot of Send Connector?
Will SzymkowskiSenior Solution ArchitectCommented:
Send Connectors are used to send mail. You would typically have them setup to point to a smart host or use DNS records for mail routing.

If you do have a perimeter device like a smart host you will also need to have proper firewalls setup.

Start with Message Queue see if the messages are queuing up. It should also provide an error message if they are not going out.

This should be a key indicator as to why your mail is not sending.

Also make sure that your domain is not blacklisted.
