I think you may have to recreate the SMTP virtual server under the exchange adminintrator.

Exchange administrator -> Server -> server name -> protocols -> smtp.  Document the existing settings, delete the virtual server, create a new one.  

This often resolves this type of problem when a new network card is installed.

Hope this helps.

Wow.. missed that one.

Exchange administrator -> Servers ->connectors -> smtp connector.  Document the existing settings, delete the smtp connector, create a new one.  

One more thing.. Exchange administrator -> Server -> server name -> protocols -> smtp -> smtp virtual server -> advanced -> make sure you have the FQDN set properly (mail.domain.com) and that check dns comes back with a valid domain name.

sorry for the confusion.

There are two smtp virtual servers. One is under Protocols - smtp - default smtp virtual server and the other is under  Connectors - new smtp virtual server. Which one to delete and replace?
0
 
msincorpCommented:
The one under connectors should do it.

Also, make sure you check for valid FQDN under the protocols -> advanced tab.

I deleted the virtual server under connectors and filled in the data but one are won't let me finish. It says "You must specify a smart host" for the name. I put default smtp virtual server but it won't take it. What is it looking for?
0
 
sergenetAuthor Commented:
Under general tab it is asking for a name.
0
 
msincorpCommented:
ok.. there are 3 required elements in the smtp connector:

1) A name for the connector (can be anythig, so make it meaningful to you)
2) The address space to "serve" usually set to SMTP and an "*" to indicate all domains
3) A local bridgehead server (usually set to your server)

If you are using a smarthost (one of your ISP's mail servers, or a 3rd party mail server) to send your mail, you will have to select that option in the "forward all mail through this connector to the following smart hosts".  This is only necessary if your mail server is NOT sending the mail directly.

Almost there.

Ok I did all that. Do I have to restart anything?

msincorpCommented:
under services, find the IIS Admin service and restart all.

sergenetAuthor Commented:
I restarted information store and still no emails. The queues are growing. Should I do anything to the other virtual server?
0
 
msincorpCommented:
ok.. right click on the largest queue, and select "force connection".  see what the message is and post it here.

did you verify the FQDN settings under the smtp server -> advanced tab?  starting to sound like a DNS issue.

sergenetAuthor Commented:
fqdn is set at mail.onyxarchitects.com and all messages (54) are under pending submission. Nothing happens when I force a connection. How do I check for dns problem? Thanks for staying with me.
0
 
sergenetAuthor Commented:
I do a dns check for the fqdn and it comes back domain name is valid.

msincorpCommented:
ok.. silly question, but here goes... when you replaced the network card did you set the IP address to a static IP?  was it the same as the old network card?  also, pay particular attention to the default gateway setting, is it set to your router / firewall?  can you get on the internet from this system?  can you "ping" other devices on the network?

don't worry... we'll get it sorted out.

Please confirm also that the following services are installed and running:

Microsoft Exchange Information Store
Microsoft Exchange Management
Microsoft Exchange MTA Stacks
Microsoft Exchange Routing Engine
Simple Mail Transfer Protocol (SMTP)

let me know.

Hows your disk space on this volume?  is it formatted as FAT or NTFS?

I found a microsoft article (http://support.microsoft.com/kb/284204) that describes the error code but it might not be related because it talks about disk space.  Here's the short version:

Numeric Code: 4.3.1

Possible Cause: This code may be caused by resource problem such as a disk full condition. This code may also occur if your Simple Mail Transfer Protocol (SMTP) queue is on a File Allocation Table (FAT) partition and the service has reached a Windows-imposed limit on the number of concurrent file handles that can be opened by the SMTP Service. In this case, instead of receiving a disk full error, you might be receiving an out of memory error.

Troubleshooting: Make sure you have sufficient disk storage, and try to operate your Exchange Transport queues on an NTFS partition.

Take a look at the artice and let me know what you think.

Ok, all the mentioned services are up and running. The ip is static and I can ping the entire network and have internet access. The volume is ntfs and has plenty of room. I saw that article already and it does not apply to me. The only thing I noticed is from a certain site, Network -tools.com, if I do email verification it comes with an error "No domain specified"  this could be a clue.

Exchange administrator -> Server -> server name -> protocols -> smtp -> default smtp virtual server -> access -> relay -> check "only list below" (make sure it is the internal IP address of the mail server) -> check "allow all computers......"

then restart the IIS service (take the restart all services option).

Now the queue is empty. I tried to send an internal email and it is just sitting in the outbos folder. I clicked on send/receive but that did not help.
0
 
sergenetAuthor Commented:
I was mistaken about the queue. The smtp service had not started and after starting it the queue is back at 68 and my email went out and joined the rest of them (in the queue).
0
 
msincorpCommented:
can you "delete" the messages in the queue?

also, is there any chance of restarting this server after the messages are removed?

msincorp
0
 
sergenetAuthor Commented:
I have no choice. Have been working on this for 14 hours non stop. I will delete the messages and restart the server. I have to let everone know so they get off the server. It will take about 15 min for the server to restart.

have you tried the exchange best practices analyzer?

this will give us some insight.

looks like it could be your swap file (paging file) causing the error.  are you sure about your disk space?  do you have two volumes?  a system volume and a data volume?  could be your system volume is running out of disk space while you have plenty on the data volume.

Let me do some more checking on my lab computer.

sergenetAuthor Commented:
The Filter folder on the exchange volume had grown too large and was the cause of the the problem. Deleting some of the older files resolved the issue. Thanks for all the help. You get all the points since you did suggest disk space problems could be causing the mail to fail.
