>>What you are saying makes sense. However, my ASP.NET application runs in anonymous mode. And from the sample code Bonnie posted for me it looks like CreateEventSource needs to be done under a valid authentication. That is, LogonUser() method should be called. So, writing to event log might not be available option for an anonymous mode application.

I understand, Bonnie. But in my "world", ITs rarely, if ever, assist me. My applications are given a very limited access, basically only to the database (VFP). And to ask them to enter their admin password would be a challenge. Most of my IT "support" know very little about .NET or ASP.NET applications; they are network engineering or network administrators. And they are concerned that their passwords will be used (maybe not intentionally) in harming their servers. This is why I often have to jump through hoops to get something done. Not to say that I give up to try your approach; if anything but to learn how to do it.
