I'm hoping someone can shed some light on an issue for me.

I have a working site. ASP, VB, running on network solutions IIS shared server.

So I was asked to move the site to a different network solutions site. They are bot nsHosting accounts. Looking int he account, they seem the same.

Well, when I copy of the files, I'm getting this error.

 Security Exception
Description: The application attempted to perform an operation not allowed by the security policy.  To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.

Exception Details: System.Security.SecurityException: That assembly does not allow partially trusted callers.

Source Error:

Line 117:            Response.Write(ex.ToString)
Line 118:        End Try
Line 119:    End Sub
Line 120:
Line 121:    Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click

1st, I find it weird that it works on the same hosting platform till I move it to this new account.

As a test I moved it to and IIS account we have with ixwebhosting. Changed the names of the hard coded directories and worked immediately.

network solutions says you must right code for partial trust when I email them, but they wont say why it's not complaining on one server and not the other.

Any help would be appreciated.
