SMTP Failure


I have several SBS 2003 servers, that today 23/03/2009, 9 had the same issue the SMTP Service starts but the Virtual SMTP in the exchange console does not, and the following event is logged.

Event Id:115
The service could not bind instance 1.  The data is the error code.

For more information, see Help and Support Center at

0000: 40 27 00 00               @'..

the only way I can get the SMTP working is by running a
iisreset /stop
then start the simple mail transfer protocol
after that run a
iisreset /start
and the system works until the next restart.

there is nothing is using the port 25 i ran a netstat and confirmed this. I have also remove antivirus software just in case, this to had no effect. I have checked there hasnt been any windows updates. I am a loss please assist.

Do you have multiple SMTP virtual servers configured in IIS?

Hi JJ,

The virtual SMTP is configured in the exchange console, I see no configuration in the IIS for SMTP
