ASP.NET keeps forcing us to restart IIS

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi;

We keep having to restart IIS after ASP.NET kills it. Below is what we
have in the event log. Any idea what the problem is?

Windows cannot unload your classes registry file - it is still in use
by other applications or services. The file will be unloaded when it
is no longer in use.
