Hi,

I'm developing an asp.net application which logs the error in case of
exceptions.
In case of exception i'm getting the following error:
Error loading an Event Sink of type
'Microsoft.EnterpriseInstrumentation.EventSinks.LogEventSink'. The Event
Source of name 'Application' will not write events out to this Event Sink.
The following exception was returned during the load:

System.Reflection.TargetInvocationException: Exception has been thrown by
the target of an invocation. ---> System.ArgumentException: An error occurred
determining if the Windows Event Log source of Application (Loan) exists on
machine .. This may be due to an incorrect machineName parameter. --->
System.Security.SecurityException: Requested registry access is not allowed.
at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable)

String machineName, Boolean readOnly)

machineName)

Can you please help me with this.

Thanks in advance

The error is >>System.Security.SecurityException: Requested registry access
is not allowed<<

Writing to the event log only works if you have registered your event
source. With the Enterprise Library, this happens when you install your
app. If you used XCopy install, then you didn't register the event source.
So the EL tries to register it when you run the app. but that requires
access to the registry.
ASP.Net uses a machine account that doesn't have the right to write to the
registry.

You need to install your app.
