I wanted to share a very quick and convenient way to update permissions in the event log.
1) Run Regedit.exe
2) Navigate to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog
3) Right click on the Eventlog folder and select Permissions.
4) I wanted to allow ASP.Net to write to the event log so I added the ASPNET account and gave it full control.
