  • Is a total reinstallation absolutely neccesary if IIS service is damaged ?

    Problem : Exchange 2003 arrested due to the absence of the IIS Service

    I have been asked to examine the case of a Server which has been running perfectly until recently the responsible in charge found that the VPN and Exchange was no longer functioning.
    There was an evident lack of space on the C: drive (due to a never purged Bad Mail directory) and this must have coincided in some degree to the malfunctioning. However the IIS service seems to have literally vanished.
    Services shows no sign and Server Administration - Add role states that IIS is not installed
    The guy who was looking after the Server had tried to use the disk cleanup to gain space and though unusual it is perhaps possible that something happened when he authorized (as Admin) the removal of ‘rarely used’ programs etc. Surprisingly no warning was given during the process.
    On my arrival I noticed this and also the fact that the most recent attempts to backup Exchange seem to have failed. Implying that their Data in the pub folders may be compromised.
    I would like to know if :
    1. It is obligatory to reinstall Exchange due to the lack of IIS.
    ie : full uninstall, reinstall of IIS and Exchange etc
    Or are there any chances of avoiding a full reinstall and recovering the original configuration despite the poor conditions ?
    I realize that this is not really very informative but I have not had enough time to examine the Server.

    2. If it is not possibile, after the reinstallation of IIS and exchange, if the old pub files are in an inconsistent state what is the best approach for opening pub files when inheriting these files in such a condition, apart from eseutil Ms Disaster Recovery Analyzer Tool and the last resort of expensive SW ?
    I am aware of course of the MS Disaster Recovery manual etc but I was wondering if there were any other useful approaches,
    Thank you

    The Exchange installation makes changes to IIS, which are only made during the installation process. If IIS has been removed or damaged, then a reinstallation is required, following the KB article on the process.
    A reinstallation of IIS alone is not enough, as it will not be integrated with Exchange.

    The options you have indicated for recovery of the data are the only ones available. Exchange 2003 is very old, so most knowledge is known about the product. If there was an easier way of getting the data back, it would have been found by now.

      Re: Is a total reinstallation absolutely neccesary if IIS service is damaged ?

      Hello

      Please accept my apologies for the late reply, I checked the Forum a little later and saw no reply at first and received no advisory Email, (strange, I thought I had set the option on), I was then occupied for the last three days with another job.

      In the meantime I have had to examine this problem and unfortunately it seems to be a little more cumbersome than expected.

      The reason for asking was that there are several proposals/suggestions for repairing IIS (with or without Exchange) around the net but I was hoping for a special tip from the experts here ... other than that those found in the typical KBs 320202 and 325889.

      The fact is that after several trial runs I am having problems reinstalling IIS.
      What should have been relatively simple is becoming a real pain ...

      Premise : Exchange is offline and the stores are currently unmountable for the above mentioned reasons, IIS is not loaded and will not reinstall.

      1. I made an Image of the server and saved it to a remote location.

      2. With a couple of NTBackups (Complete Disk copy well before the Crash) I tried restoring the server to a working state before the Crash.
      This did not recover the state of the server (Exchange) at the date of the backup. Seems that restoring is not really restoring, not overwriting the current state.

      3. At this point I tried the method KB320202.
      Stop Exchange Services, Uninstalled IIS, Reinstalled with SP update etc.
      Each went without error and yet the IIS service is not activated, the SMTP
      and NNTP services are but of course without effect. [IISAdmin not present]

      Tried another approach using the setup.exe /disasterecovery switch as suggested in various threads, even here, but this failed also.

      Could you explain where I may have gone wrong or how I might resolve this IIS reinstallation issue so that I could reinstall and hopefully reload the old Exchange Store ?

      There are several event errors such as 1029 Metabase Access, 7003 ISSAdmin.
      I suspect that uninstalling Exchange will not resolve the problem but I may well be wrong. Are there any tools that that might be pertinent to this case ?

      A brief note added here:
      [To complicate things further, due to the fact that the clients firm was/is rather small and for some reason SBS was not considered, the server on which Exchange 2003 is installed is the one and only domain controller.
      Mail is being temporarily 'managed' by one of the employees using Email redirection]


      Any suggestions would be most appreciated.
      Thank you.

        Clutching straw idea here, but can you add a temp second DC, sync AD etc and then totally rebuild the old Server. An evaluation copy of Server 2003 could be used as the temp DC.

        Depending on how old your Server hardware is, this may be a good time to consider upgrading possibly to SBS 2011.

        Sorry I can only provide options but Simon may quite likely come up with something to help. He is after all an extremely knowlegable Exchange Guru.
        1 1 was a racehorse.
        2 2 was 1 2.
        1 1 1 1 race 1 day,
        2 2 1 1 2

          Given what you have done, I think a DR install of Exchange on a fresh build is now your only option.

            Please excuse the delay, just got back.
            Thank you both for the assistance and suggestions.

            Since I can return to the state of the server just after the upset (= the state in which I found the server the day I was called) using the Server Image I made, may I inquire if you are both of the opinion that, in this case, restoring IIS and then returning to an Online state with Exchange using the usual methods is practically impossible (ie hopeless) ?
            What could impede a clean reinstall of IIS and the consequent recovery of Exchange using the backups ?

            [I had already intimated to the client that this could be a possible occasion for a full reinstall and also of the possibility of SBS]

            Due to the actual use of the server I doubt that the Firm will consider changing to SBS for the moment, it is expected that by Summer they upgrade the Server.

            Regarding Simon's comment: Given what you have done, I think a DR install of Exchange on a fresh build is now your only option.
            Does this mean that you think there is little else to be done on this server, due to my description of the symptoms here, or that your suggestion would be the most efficient in time and cost or that my attempts were inappropriate and out of place?

            I noted your interesting comments at : http://forums.petri.com/showthread.php?t=21430

            But all things said even here, is one not going to spend quite a while building a setup similar to the description in your post ?
            Just for statistics if you were starting from nothing at a clients place, how much time would you expect to employ to complete the process ?

            I cannot help wondering about how one could resolve the problem with IIS and if I am not missing something, I would have thought that it must be solvable. MS seems to indicate that it should not be too difficult.

            Thank you both for the advice.

              A reinstall of IIS using the KB article should have resolved the problem. The fact that it didn't would tend to point to a problem with the Windows installation. Therefore DR is the only option, as that means you can use the same machine name, which allows the databases to mount. Exchange databases are very sensitive to machine names, Exchange org, domain names etc, so any rebuild needs to be as close as possible.

              SBS would be a bad move at this stage because of the limitations of the product.

              I am not really sure why you have linked to that older post of mine. That is for getting a copy of the domain for DR practise. I don't see its relevance to this issue.

              Simon.

                Simon.
                Thank you for your prompt reply.
                The reason for the reference to your post (The way that I do this is to use virtual machines. Build the domain controller in a virtual machine .... ) was simply the fact that 'you made it look so simple' to arrive at the client's place with a portable machine, load a VM or two, with Exchange, with the correct settings and the data, and recover everything in a question of minutes
                I do in fact have a ESXi Server at the office with W3K and Exchange VM's for testing but I strongly doubt I could fix all this as you describe, even in a question of hours.
                Best wishes and thanks again.
