DCOM errors when sending w/Exchange

By NateH ·
Hi all,

Running SBS2003 w/Exchange. New installation. Client is randomly getting emails bounced back. Sometimes they make it through, sometimes not - to the same legit address.

I checked the error log and get the following error:
----------------------------------------------
Event I 10009

DCOM was unable to communicate with the computer mx-a065a23.pas.sa.earthlink.net using any of the configured protocols.
----------------------------------------------

This is supposed to be going to a legitimate recipient(I have tested this address several times).

I have never seen this type of error and cannot find anything in Microsoft regarding this.

I don't understand what DCOM has to do with SMTP or exchange communicating with other servers.

HELP!!

Nate

wonder what the bounce back error msg is?
does this happen from any client or only one? what os/sp on bad client. what sp on sbs2003.
dcom used to be 'network ole' from what i can glean, and is ms communications protocol
it is not only this one internet address is it?

Hey try this: -I found this link using the Google site their searh engine did a better job of finding this document that the MS Support search engine. Go figure...lol ;-)

http://support.microsoft.com/kb/290512/EN-US/

There is another link at the bottom of this page that discusses how to increase the number of available ports...

I just found this on the MS support site, I am having a simlar problem on communications between a server and one specific workstation...good luck.
