  • IISreset

    Hello guys,

    I need help here. We are currentlly running windows 2003 w/latest SP and Exchange 2003 w/sp2. We having this intermitting problem with our mail server.
    Here's the problem, in every few days, our Information store will hang, all our users cant rec'v any email. We can send out, but dont know if went out or not. We dont even rec'v any local email neither.

    Now, here's the weird thing. if I enter "IISRESET" on the command line it stop and restart the service, everything back to normal. Why this happend?
    I have AV program running and no we dont have any virus.
    Anyone can help, I reallly appreciated.

    IISRESET will restart SMTP as well as the WWW service (OWA).

    Are you using OWA? I'm betting SMTP is the issue.

    I'm not an Exchange guy so one of our experts can jump in and save me.

    Google on some combo of

    iisreset exchange smtp "information store" hang
    and see what you find.

    Here is a link on IISReset that caught my eye:

      I dont know whats really causing it. If I "IISreset" it works fine.
      If I try to stop the SMTP on the Services , it will hang and same goes with Information Store. If I know those 2 services get hung. Thats when I use the IISreset to do the job.

      See, right now everything is work fine and dandy, I'm going give another few more hours and see if hang or not. Standy by.

        Problem is, MS intertwines so much crap into a single process you can't kill SMTP by itself as there is no SMTP.EXE -- it's all InetInfo.EXE

        So not an OWA site? Any other IIS "stuff" (SharePoint, Frontpage, ASP.NET, WWW, NNTP, FTP too) happening on this server?

        Also, any timing issues when it fails and when you backup? Locking a file till something craps out?
        Cheers,

        Rick

          Oops, I missed that part. Yes, we do have OWA running as well.
          (No "www,nntp,ftp,frontpage,sharepoint,asp.net" are runnnig).

          My backup doesnt start till 11:30pm from Mon to Friday..
          Oh wait, let me show this screen shot. Whats these about?

            Re: IISreset

            And it doesn't fail @ 23:30 +/-, correct?

            Now you're well past my level of Exchange expertise. We'll need to wait till the Exchange gurus check in.

            As a scientific method kind of guy, what's your MTBF? Short enough to run an experiment like disable OWA and see if the problem goes away?

            That's all I have to offer for the moment.
            Cheers,

            Rick

                What else is on the machine?
                That is classic sign of something hanging on to the process. AV is the prime suspect, particularly if it is produced by Symantec.
