You do have a machine.config file, otherwise you wouldn't be able to
run .NET. Look in the
{WindowsDirectory}\Microsoft.NET\Framework\v1.1.4322\CONFIG folder.
But that is besides the point.
You are are at cross purposes here. You have set up your ASP.NET
account as an administrator, but by turning on impersonation, you are
actually running the app under another identity (whatever is set in
machine.config, likely the logged on user as determined by IIS, which
is probably the anonymous user who has no rights).
You can find out what user account you are running under like so...
System.Security.Principal.WindowsIdentity wi;
wi = System.Security.Principal.WindowsIdentity.GetCurrent();
You can then either try turning off impersonation, and letting your
APS.NET administrator account (BTW, giving your ASP.NET account admin
priveleges is a bad idea), or set impersonation identity to a more
powerful user (also not a great idea).
Better idea is to create the event source with an app running under an
administrative user privileges. This is what is causing the error.
Writing to the event log doesn't require registry access, only
creating the source does.
Even better idea is to download log4net
http://logging.apache.org/log4net/ and not have to worry about it
yourself. You'll see there is an EventLog appender.
