SMTP Server error - I'm running out of ideas

By gm ·
I have a 2 month old wireless network (3 x desktop, 2 x laptop). Last week we were suddenly unable to send email from any computer, we received the following errors:

"The TCP/IP connection was unexpectedly terminated by the server. (Account: <account name>, POP3 Server: <server name> Error Number:0x800ccc0f."

"The connection to the server has failed. Account <account name>, server, <server name>, protocol, port 110, 0x800ccc0E."

We can not send any email. We can still receive email and access the internet. The rest of the network is working correctly.

All the computers are running Windows XP pro. They are linked with a Dell wireless router/ access point which is wired to an ISDN router, connected to the phone lines. We have tried Outlook & Outlook express 2000 & XP

I have tried using different email accounts with different mail servers but have the same problem which makes me believe the problem lies somewhere on the network or each computer.

I have tried using the system restore utility to roll back to a few days before the problem started but this did not work.

I have stopped Norton antivirus from scanning outgoing email and have tried removing it completely from one computer but we still have the same problem.

Nothing has been changed on the network, hardware or software. The only thing that may have been added is a Norton virus update.

Any ideas would be appreciated

i think this article from MSKB basically says check your firewall and call Symantec...
Microsoft Knowledge Base Article - 813514
OL Error 0x800ccc0d or 0x800ccc0f When Receiving and Sending E-Mail
View products that this article applies to.
When you try to send and receive e-mail, you may receive one of the following error messages:

No connection could be made because the target machine actively refused it

The server could not be found. (Account:account name, POPserver:'mail', Error Number: 0x800ccc0d)

Task 'server name - Sending and Receiving' reported error (0x800ccc0f): 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP). The server responded: ? K'

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account. account name, Server: 'server name', Protocol: POP3, Server Response: '+OK', Port: 110, Secure(SSL): N0, Error Number: 0x800ccc0f

Task 'SMTP server name - Sending and Receiving' reported error (0x80042109): 'Outlook is unable to connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'
This error message occurs when Microsoft Outlook or Microsoft Outlook Express cannot establish a connection with your e-mail server.

('call your isp' that's the ticket...)
To work around this problem, use one of the following methods as appropriate for your situation.
Method 1: Confirm That Your E-Mail Server Settings Are Correct
For information about the correct settings for your e-mail server, contact your Internet service provider (ISP) or system administrator.

Method 2: Configure Firewall Software
Configure your firewall software to grant access to the Internet for the following files.
For Outlook Express: Msimn.exe
For Outlook: Outlook.exe
By default, most e-mail clients have to have outbound access on port 110 and inbound access on port 25. For more information about the ports that communicate with your e-mail server, contact your ISP or system administrator.
Method 3: Check the Symantec Web Site for Additional Suggestions
If you have the Norton antivirus e-mail feature enabled, you may have to do additional configuration to use Outlook or Outlook Express with the Norton antivirus e-mail feature. For more information, visit the following Symantec Web site.

well hummm... first question that comes to mind is your firewall. Do you have a firewall on each computer or rely upon the wireless router for firewall protection. If you have a firewall on each computer, does it allow Outlook access? Norton Personal Firewall automatically setups known trusted programs "but" sometimes it doesn't do a thorough job. You can run a program scan manually to verify those program you want access to have access. Second is do you have the wireless firewall allowing port 110 and port 25 inbound and outbound TCP/IP traffic? Third is have you checked the FAQ on your wireless router for bugs in the firmware. It's quite possible you have buggy firmware where if you use PnP port fowarding, connections are dropped unexpectantly [Linksys routers had this bug in their firmware with PnP port fowarding]. Next is authentication problems with the POP3 server at the ISP end. Maybe they changed something. It's always possible.

another possibility is internet congestion. I've occasionally could not access a site simply due to huge demand. Possible that your ISP was expericening larger than normal demand. Could be they were doing maintenance.

Thanks for the help, I do rely on the wireless router for the firewall. All the pop3 & smtp settings are correct. Not sure how to check if the wireless firewall allows access on the ports but it was working fine until last week and nothing was changed. It may be the firmware as a connection has been lost to 1 laptop before for no aparant reason. How would I check/change the firmware?
I have tried different ISPs and mail servers but we still have the fault.

I'm having the same problem too, but I am able to send to a couple of addresses but unable to send to the rest!! Because I have a pipex account but using adsl from British Telecom, my pop3 setting is but my smtp address is

If I plug the laptop directly into the adsl line (via usb) then it works fine but once I start using the wirless router instead then i get the problem. I've rang belkin and BT but no one can help me.

I just ran into this problem two days ago.
I am running Norton Internet Security 2004. Last week email was fine. I downloaded the latest and greatest updates and rebooted. Went to check the email and was unable to connect and received a timeout error. This kept happening for a day or so and then I saw an alert that stated someone was trying to get into my PC (it is connected via high speed so I am sure some knucklehead was just poking around). I went to clear the security alert and realized I could not as the kids account was logged in (they are not admins for NORTON). I logged off the kids account logged in to my admin account for NORTON and cleared the alert. I went to check my email and the first time it still failed. I went to hit the send recieve again and noticed a pop up from NORTON that stated it was configuring a rule to allow the email program to access the internet. It appears that with this newer version, it has to create or you need to create a rule that allows email to access the net. The previous version of Norton I was using never did this. After the rule was created I am able to get my email again regardless of the account I use. If you are using NORTOn firewall (you may have to go in and open that particular port again or create a rule that does it automagically when your email client tries to send out that port.
