In the event viewer, around every 5 minutes I am getting the event described here: http://technet.microsoft.com/en-us/library/cc735145(WS.10).aspx
"FailedRequestTracing module failed to create directory '%3'. No logs will be generated until this condition is corrected. The problem happened at least %1 times in the last %2 minutes. The data is the error."
The fix is supposed to be allowing IIS_IUSRS write access to that directory.
Not only did IIS_IUSRS have write access, but I have also allowed IUSR, NETWORK SERVICE and the plesk panel IUSR accounts for all 3 of my domains, and I am still getting the error.
I can't help but think this is something really stupid with Plesk Panel. Fairly sure that every weird problem I've had has stemmed from Plesk, unfortunately my server was pre-configured with it. Is there a way to find out what user IIS is trying to access the log files with so I simply grant it permission?
