I have four servers in a clustered non-sticky environment that is serviced by a single state server. I noticed that the app loses session when it hits a particular box 90% of the time, and 10% times on the other boxes. I observed the machine keys, and they are the same in all the boxes. I also checked the application path in IIS, they are also the same. One thing which i noticed using the IIS Metabase Explorer was that the main problem server did not have a value for logpluginclsid for the web application; whereas the other servers do. Is this the source of the problem?
Thoughts?
