HTTP 500 Errors in Dashboard and ASP.NET 32-bit Mode

Over the past few years, I’ve seen a few instances where ProClarity Dashboard and Kerberos just don’t seem to get along – no matter how much configuration or troubleshooting is performed.  One of the symptoms I see is an HTTP 500 error when users try to browse the Dashboard.  Our esteemed Sean Flanagan recently solved a similar case and the answer was to verify that IIS ASP.NET was configured to run in 32-bit mode instead of 64-bit mode.  IIS was already configured for 32-bit mode since ProClarity is a 32-bit only application.  This solution may have been the cause for some of the past failures I witnessed.  Here are the instructions for making the switch.
