service security with even log problem

[Brian Henry]

Has security changed with accessing the event log through a local service in
..NET 2.0? in 1.1 i did this

If Not Diagnostics.EventLog.SourceExists("BDBHOST") Then

' create log

Diagnostics.EventLog.CreateEventSource("BDBHOST", "Benefits Service")

End If

Diagnostics.EventLog.WriteEntry("BDBHOST", "The Benefits Host Process was
successfully started", EventLogEntryType.Information)

and it worked perfectly fine in the OnStart method of the service... but
when doing that in .NET 2.0 it fails with an event log entry in the
application event log saying this

Event Type: Error
Event Source: BHOSTPROC
Event Category: None
Event ID: 0

Time: 2:19:12 PM
