Getting exception from CreateEventSource

[Philip Colmer]

I'm trying to set up event logging in my web service. The code is as
follows:

Const AppName = "Fred"
Dim objEventLog As New EventLog

Try
'Register the App as an Event Source
If Not objEventLog.SourceExists(AppName) Then
objEventLog.CreateEventSource(AppName, Nothing)
End If

objEventLog.Source = AppName
objEventLog.WriteEntry("Test")

LogOutcome = ""
Catch Ex As Exception
LogOutcome = Ex.ToString
End Try

I'm getting an exception at the call to CreateEventSource:

System.Security.SecurityException: Requested registry access is not allowed.
at Microsoft.Win32.RegistryKey.OpenSubKey(String name, Boolean writable) at
System.Diagnostics.EventLog.CreateEventSource(String source, String logName,
String machineName, Boolean useMutex) at
System.Diagnostics.EventLog.CreateEventSource(String source, String logName,
String machineName) at System.Diagnostics.EventLog.CreateEventSource(String
source, String logName) at
QuarantineService.QuarantineValues.LogOutcome(String strUser, String
strComputer, String strOutcome)

I'm not entirely sure what to do to resolve this. The web service is running
under the default app pool.

Hi

Based on my research, by default, the user token of the ASP.NET worker
process is ASPNET (or NetworkService for applications that run on Internet
Information Services [IIS] 6.0). The problem in the "Symptoms" section
occurs because your account does not have the correct user rights to create
an event source.

Here is a KB article you may have a look about the detailed resolution.

Many thanks for that. I've created the source installer and it has fixed my
problem.
