IIS logging is enabled by default, and the default path for the log files is on the C:\ drive. Over time, the drive becomes full, which creates a serious downtime risk on the server. To prevent this situation, disable IIS logging.
 | Tip: If you prefer to keep IIS logging active, change the location of the IIS log files. |
