I have a Windows 7 workstation whose security log is overflowing with the following errors:

Audit Failure 3/31/2010 2:00:50 PM Microsoft-Windows-Security-Auditing 5157 Filtering Platform Connection "The Windows Filtering Platform has blocked a connection."
Audit Failure 3/31/2010 2:00:50 PM Microsoft-Windows-Security-Auditing 5152 Filtering Platform Packet Drop "The Windows Filtering Platform has blocked a packet."

These are not unexpected events; the firewall is expected to drop unsolicited traffic. However, I can't figure out how to tell Windows to stop writing these events to the security log. I've seen this problem before and have been able to find an answer with the use of Google, but I wasn't able to locate on this this time.

Thanks!
