You need to find out what account credentials the application is running
under when access is denied. The access denied means the account
credentials the application is running under at the time of access to
what E: is mapped to doesn't have the permission to access E:.


You have an account permissions issue that the application is using to
access E:.
 
To follow up, here is some code to return the user under which the code is
running.

Most likely , "ASPNET", and that account needs rights granted to it to write
files out.



private string FindIIdentity()
{

try
{

string returnValue = string.Empty;

WindowsIdentity ident = WindowsIdentity.GetCurrent();
returnValue = ident.Name;

try
{
returnValue += " on " + System.Environment.MachineName;
}
catch (Exception ex)
{
Conditionals.Trace.WriteMessage(ex.Message);
}

return returnValue;
}


catch (Exception ex)
{
Conditionals.Trace.WriteMessage(ex.Message);
return "Error Finding Identity";
}

}
