How To Set-up a Network Client File Location

With the introduction of the configurable client file download path on the LOWIS client updater, version 450 and later, some customers expressed an interest in using a network location as their Client File path.  Due to Microsoft .Net security restrictions, the operating system requires that any network location be fully trusted in order to launch an executable file.  If a user attempts to use a network path that is not fully trusted, the LOWIS client fails to launch properly.

To fully trust a network location you will need to use the Code Access Security Policy Tool provided by Microsoft with .Net.  For the LOWIS client you will want to set the 32-bit .Net 4.0 permissions to Fully Trusted for your network location.  You can typically find the file by going to the command prompt and putting in "cd %SystemRoot%\Microsoft.Net\Framework\4.0.30319\".   The argument you want to use to enable Full trust are: "caspol.exe -pp off -m -ag 1.2 -url file://<serverlocation>/* FullTrust"".
