 hello experts,

I have an application built in .Net. The client computers have the .Net Framework installed. I can run the application locally with no errors, however. if i put the exe on a network drive it will not run. i always get

The application attempted to perform an operation not allowed by the security policy. the operation required the SecurityException. To grant this application the required permission please contact your system administrator, or use the Microsoft.Net security policy administration tool.

Request for the permission of type Sytem.Security.Permissions.SecurityPermission, mscorlib, version=1.0.3300.0, Culture=neutral PublicKeyToken-b77a5c561934e089 failed.

I have already done

-gave the app a strong name with sn -k
- addde an AssemblyKeyFileAttribute n then recompiled
- Trusted all versions with full trust with the same key (using .net wizards trust an assembly)
- Enabled full trust on local intranet

the connection string i am using in the code is
SqlConnection("Data Source=servername;Initial Catalog=DBasename;User ID=userid;Password=xxxxx");

I am using visual studio 2003, sql server2000, and windows server 2003

Try giving the app full rights on the local computer as well.

It's a quick and dirty test, but it should work if you provide full trust on both the local computer and full trust on the local intranet as well.

Thanks a lot topdog770 for the reply.

I already gave all permissions at machine level and user level. I have tried setting all zones(local intranet, my computer, strong name,.......).

Do i have to do anything on client machine. How do we give full trust on the local computer?

Thank You

Yes--just to confirm--on a computer trying to run the app from the network getting the security exception--go into control panel, administrative tools, Microsoft .NET Framework 1.1 configuration, Runtime Security Policy, Adjust Zone Security, Make changes to this computer, Set My Computer to full Trust and Local Intranet to Full Trust

Try running the application

Ok!  I'm making this too hard and forgot the most basic thing of all... and it gets me every once in a while too..

Install the .NET Framework on thier computer and then set permissions and then, finally, the app should work.
