Code Access Security Issue for web farms with a separate file server

We built the site on DNN 4 with 3 web servers a clustered file server and clustered SQL boxes.  (The site does 17 million pages a month)  We ran inot some permissions issues with using the separate file zserver which houses all of the files needed to run DNN.  The fix is below.

As far as I can tell, the issue your experiencing is the result of the default .NET Code Access Security (CAS) permissions not allowing remote code to execute.  This issue is described in the following Knowledge Base (KB) article.  This article hasn't yet been updated for .NET 2.0.  The error looks a little different on .NET Framework 2.0 and unless you have the .NET 2.0 Framework SDK installed, you won't have access to the Microsoft .NET Framework 2.0 Configuration MMC to make the required change, so I've included the equivalent caspol command below:

PRB: "System.Security.SecurityException: Security error" Error Message when the Virtual Directory Points to a Remote Share in ASP.NET

caspol -m -ag 1 -url "file://\\fileserver\share\*" FullTrust -exclusive on
