I have some ASP.NET code which calls an assembly which in turn calls a SQL Server 2000 stored procedure. It says there is a security exception and that I should contact the administrator to correct the problem. <BR>In order to try and solve the problem, I changed the trust to FULL using the .NET configuration tool. I also changed the machine.config file to <BR>use the System username instead of machine username. <BR>None of this worked. <BR>Any ideas? I really need help I have tried and looked at everything that I can think of.
