Socket error 10061

One node on my network cannot send email, it can receive. All other machines can both send and receive using the same ISP. When trying to send, I get the following message:
"The connection to the server has failed. Account:your account.
Server:your smtp server, protocol smtp, port 25,
secure (ssl): no
Socket error: 10061, error number: 0x800ccc0e"

MS KB article Q191687 leads me to believe that my mail client, in this case Outlook 2000 and Outlook Express, thinks it is attached to an Exchange Server. It cannot find the server, so it cannot  send. No problem with pop3 on port 110. I have reinstalled Outlook and have tried Outlook express, no go.

I have tried all of the fixes suggested in various MS KB sheets, except for those that tell me to turn on the SMTP service on my Exchange server or some such other thing related to a mail server.

I assume that there is something in the Registry that needs to be changed. If anyone has experienced with Port 25 configurability I would appreciated the help or a pointer on where I can go for more info.

Just a shot in the dark here:
Perhaps you could look for this in the registry and edit it to reflect server:

You may have something loaded out of order, but let us return to basics. Reboot and start OE5. Select Tools on toolbar at top.

Under Accounts, tab Mail, select the account (name) and properties.

Verify the eMail address of user, then Servers. Incoming mail s/b POP3. Now verify that the Server Information for specifying Incoming mail and Outgoing mail is correct. They are likely different servers. The first is POP3 source, which I assume is correct the way the question is worded.  The Outgoing mail, SMTP (using port 25) should be the DNS name of the server used to send mail to the outside. This is possibly redirected to your exchange server incorrectly. If you have forgotten what it is, just go to a machine that is sending OK, and see how its servers are named, and you have it.

Done.      Done?      (same kind of process for Outlook)

If not, odds are that some install or upgrade ran incomplete or incorrect, and you may be better off simply rebuilding the machine to better ensure total integrity of all applications.

don't have an exchange server. This machine is set up exactly the same as my other machines, all of which function correctly.
thanks anyway.
I am really looking for a registry fix that has to do with port 25, if there is such.

Find out if you can telnet to port 25 on the SMTP server --

telnet servername 25

If I remember correctly 10061 means "Can't get there from here."

If you can't telnet to port 25, that means something is blocking the connection -- either a piece of software on the client (personal firewall or such) or something between the two machines is blocking the connection (proxy server, router with ACLs configured, etc.)

If "your server name" is being reported rather than the actual SMTP server name, try setting the SMTP server to the IP address of the server.

Still think that a red herring. This port 25 is default that likely all use. Other workstations are fine, so you don't need a hack job for port alternatives. The server is not found, most likely because the desktop is not configured properly. Most likely it is misspelled for SMTP - which is a different service than pop3 server or Exchange Mail. Client should not be doing Exchange, should be doing SMTP & POP3.

Possibly, the servername is given, but not the domain, and the user has configured a different domain (check IP settings of desktop).

A possible is the wiring closet which can block by user port. You can try swapping out good for bad port on the switch in the closet, but I think it is simple configuration.

I agree w/ mshivdas on the general meaning likely being "Can't get there from here."  While it can be a blockage closer to firewall, or on the firewall itself, that is less frequent IMO since it is easier there to be uniform, treating all users equal. One way that happens is if your site is also running a validation scheme. Some devices, for example, require user machine to be defined in DNS. They do a lookup and won't acknowledge you if not in DNS. Others run user authentication at SMTP server. My assumtion was, that if that was the case that you would have been so informed of the policy and had made user machine conform to it.

Again, port 25 is the proper port for protocol SMTP.

On occasion, a Microsoft upgrade or service pack goes awry. In some such cases, simply removing the tcp/ip stack, then adding it back in, becomes the fix. I do not think this applies yet, for you are not mentioning any other problems with tcp/ip access, which I would expcet if there was a problem in the stack. But stick that trick in toolkit for times when all else fails.

Each client should use same DNS server. At least they must achieve same results. From two machines, one that is successful, one that is not, go to Dos Prompt in command window and run a couple commands:

Ping <SMTP_server_name>

TraceRt <SMTP_server_name>

The first one should get quick answer to whether they both get same name translation to proper address. Also may indicate timing issues. The second one gets you the route info, in cases where something is awry in routing packets successfully from one place to another.
