Hi all,
I have an ASP.NET application deployed in production on 4 servers for monitoring the enterprise website features from production support viewpoint. Servers are running IIS 7.
The same application works on 3 servers as is, but it doesn't work on 1. All IIS and AppPool settings are same. This faulty machine has few extra Microsoft patches deployed.
While fiddling with IIS settings, setting the AppPool to enable 32 bit apps, the application started working on this box.
We don't get this as it wasn't ever set before and its working without this setting on other 3 servers.
Has anyone come across this situation where a recent patch by Microsoft broke the functionality resulting in such weird behavior? I was guessing probably the server has some 32bit DLL that has replaced a 64bit counterpart and so only when we enable 32 bit apps is when it starts to work.
I know all servers should be on same patch level, but unfortunately I don't control that.
