If this is a development machine or a machine you have full control over then you can set it to full trust. If you're in a medium trust hosted environment there is not much you can do but switch hosts or accept the tradeoffs of medium trust.

trust level can be set in Web.config but in hosting is usually set in machine.config

Hope it helps,

ok well it must be machine.config because if machine.config is set to medium then setting to full in web.config won't work.

best to comment it out in web.config and track it down in machine.config

also is this IIS 6 or did you install IIS7?

be aware if you have multiple versions of .NET on the machine they each have their own machine.config, make sure you are looking in the 2.0 .NET folder

on my machine I have folders for 1.1 framework up to 3.5 and each is in different folders

2.0 on my machine is in:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG folder

Hope it helps,

One more possibility is if your machines are on a domain and trust level is being enforced by group policy I don't think you can solve it with machine.config on the machines.

Hope it helps,
