New Hotfix: Run ASP.NET Without Full Trust in My_Computer_Zone

  • Article

I have been working with the product group on a new hotfix that allows you to run ASP.NET 2.0 applications without associating the My_Computer_Zone code group with the Full Trust permission set in Code Access Security. The new hotfix is available now under KB article 943598.

Pay careful attention to the KB article because it gives you the specific CASPOL commands that you need to run after installing the hotfix.

Keep in mind that the configuration changes made after you install this hotfix will affect anything running ASP.NET 2.0. For example, SQL Server Reporting Service will not work after you change CAS settings for the My_Computer_Zone. (A solution for that is available in the KB article.) SharePoint will also likely be impacted by reconfiguring CAS and we have not tested this hotfix configuration with SharePoint.

Simply installing the hotfix will not impact your applications.
