    Hi

    We have IIS installed for SMTP email service on our windows server 2008 R2 SP1. I am unable to start the [SMTP Virtual Server #1], i get an error message

    "The service has returned a service specific error code. Check the Windows Event Viewer for details"

    When i checked the Event Viewer logs and i found the below error

    "The service could not bind instance 1. The data is the error code."

    When i googled about this error i found that the port 25 is being used by another application which is why my SMTP Virtaul server #1 doesn't start.

    I did Telnet localhost 25 and i see the port is being used by hotmail. The below message when i did telnet

    220 BLU436-SMTP198.smtp.hotmail.com Microsoft ESMTP MAIL Service, Version: 8.0.9
    200.16384 ready at Tue, 21 Jul 2015 07:07:01 -0700


    How do i disbale the smtp.hotmail to use the port 25 so that my SMTP Virtual server #1 can use port 25. Please help.

    Thanks
    Arun Chanda

    Hi

    I figured out that SMTP Proxy service was using port 25 which was not allowing my SMTP Virtual Server #1 to start. I stopped the SMTP Proxy from services and my SMTP Virtaul server#1 in my IIS started working.

    Excuted the command netstat --noa in commane line tool to check the PID of the application that is using the port 25.

    From the TaskManager/ Services Tab i was able to figure out the application using the PID Coulmn. Stopping the SMTP Proxy i was able to turn on the SMTP in my IIS Server.

    Thanks
    Arun
