the application pool is set to use IIS APPPOOL\DefaultAppPool (which is the default)

using EntLib 4.1 and .Net 4.0 RC together with studio 2010 RC

Hi Chris,

Is your App logging correctly if run on debug mode? Have you already installed the EntLib InstallServices.bat? Also, check if the Identity set in your AppPool have administrative privilege to create an event source.

Hi ginkaptain,

thanks for the help. we now created our own logs in windows eventlog and with the created sources the logging works. seems that the event source used before wasnt existing and therefore it gave the errors.
