    Shared Configuration causing HTTP Error 503 on second server?

    Hello,

     I have 2 servers running 2008 RC0.  The primary server has quite a load of software installed including Exchange 2007 while the secondary server is practically fresh.  I have a very very simple site I created on the primary server and then setup shared configuration.  I am able to get the site to load on the primary server but not the secondary server.  If I revert back to local configuration on the secondary server, the site loads just fine.  This site is running in it's own application pool.  I have verified the standard permissions settings assuming that was the problem, initially.  Fairly certain this isn't the case here.  As soon as I hit the site on the secondary server the app pool fails and triggers this error. 

     Anyone else seen this problem in when setting up Shared Configuration in IIS7?

    I've read through Mike Volodarsky's articles on troublshooting IIS, which has helped me identify the Event ID of 5002 in my system event log.  However, I am unable to get anything out of the Failed Request Tracing logs.

    Re: Shared Configuration causing HTTP Error 503 on second server?

    Yea, I've seen this post and we have started the application pools repeatedly everytime this error occurs.  However, as soon as we browse the site again it kills the application pool again and deliveres the same HTTP 503 - Service Unavailable.  We were convinced that when we first saw this error message that there was a miconfiguration in the permission somewhere but we've rule that out I believe.  We've got permissions wide open at this point, in order to debug.  We've also gone so far as to narrow the site content itself down to a single default.htm as to be sure there were no .net framework components or application problems in the site causing this problem.

     If you share a site configuration, must the recipient server contain all of the exact same content locally on that server?  In other words...if my primary server (where I have exported the configuration and establed the sharing relationship) has Exchange's web applications in the default and then a seperate Sharepoint site, etc...must the secondary server (where I am consuming the exported configuration) contain those same products or sites or can those sites be stopped on the secondary server?

     Clearly we need more info on Shared Configuration and it's requirements and limitations.

     Thx,

    Your shared configuration file is probably referencing  something that is needed for the app-pool to run which is not present on your second server (eg app-pool-id user or a module dll etc) or maybe you have encrypted properties in the config file but have not exported encryption keys correctly.  You should see event log messages in system event log (under WAS or W3SVC event source) and/or application event log (under W3SVC-WP event source) which should shed more light on this.

    Regarding requirements of shared configuration - ultimately it behaves exactly like local configuration (if you can read it, of course) - so, whatever is valid locally would be valid in shared configuration.

    Re: Shared Configuration causing HTTP Error 503 on second server?

    Thanks for the response Anil.  I don't want to read too much into your reply but I believe your initial suggestion is correct in this case.  As I have Sharepoint, Exchange, TSWebApp...etc installed on the primary server but not on the secondary server.  I simply wanted to show shared configuration on one of the other simple sites I have setup on the primary server.  So the question I have - must the IIS7 servers within a shared configuration contain the exact same sites in IIS on both servers with identical application pools and modules loaded?  I assumed the answer to this was a definate yes although I'm not quite sure w/o some documentation.  If I'm wrong to assume this I will continue debugging my problems with the initial configuration.

    I'm working on a demonstration project for the Windows 2008 launch and under a bit of deadline to get this working.  So, I've taken, what I thought would be the next logical step and built out a Windows Server 2008 Core VM which is the same RC0 build as the other Windows Server 2008 VM that I plan to share the IIS7 configuration.  Yes - I am aware that there is no .net framework support in a Core instance of IIS7 at this point but for the purpose of the demo I'm sticking with straight HTM files to keep it simple.  Is this the wrong path to persue using server Core installation for IIS7 Shared Configuration?  Will I be able to do such a thing in the IIS7 instance in Core?

    Thx,

    Re: Shared Configuration causing HTTP Error 503 on second server?

    Today i´m trying to configure a IIS Shared Configuration on W2k8 x64 plataform, everything works fine, but the Application Pool in one of the server (two server) stop running after the first access with the error below:

     

    HTTP 503 - Service Unavailable

     

     

    1 - This servers work in Workgroup mode and the UNC path is another file server. 

    2 - All Service Packs and updater was installed.

     Anyone knows how can i fix this issue?
