Bug: Source not found, but some or all event logs could not be searched.

Bug:

The source was not found, but some or all event logs could not be searched. To create the source, you need permission to read all event logs to make sure that the new source name is unique. In accessible logs:Security

This can occur if a .Net application attempts to create the source at runtime, but not as an administrator. It is better to perhaps create the source ahead of time as an administrator in regedit, then just use the source in the application.

Private _eventLog As New EventLog(“Application”)
‘EventLog.CreateEventSource(SourceName, LogName, MachineName)

In registry at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application\
Add permission to Authenticated Users = Full Control

Or add to the specific key.
