Somewhere in your web.config you should have a line that reads
<trust level="xxx" originUrl="yyy"/>

That statement sets your working page to a certain trust level. If its minimal
then in your sharepoint folder (depends on wss or sps) (mines in C:\Program
Files\Common Files\Microsoft Shared\web server extensions\60\CONFIG) you will
have wss_mediumtrust.config and a wss_minimaltrust.config (i'm running wss not
sps hence the filenames).
