The account that your WebService is running under does not have write
permissions. You have basically two choices:

1) Determine the account (ASPNET, IUSR_<YourMachineName> ) that the service
is running under and grant it modify permissions on the folder where you
need to write your log. (you may need to do this both in IIS and for the
physical file folder with ACL's as well)
2) Try changing your -processModel "userName" attribute in machine.config
file from "machine" to "system". Note that this option is the "brute force"
approach and can have security consequences.
