problem with security audit log

Hi

My server is running on windows 2003 server. As this is a file server, i need to perform auditing on file accesses.

After I have enabled the object access item in the local security policy, I discovered that there are a lot of 562 and 567 entries generated in the event log. This cause the event log to grow very fast. As I can only manage the server remotely via VNC, there are many VNC entries generated every few seconds. This causes the event log to become full.

These are the common 2 entries

Event Type: Success Audit

Event Source: Security

Event Category: Object Access

Event ID: 562

Date: 9/6/2005

May I know is there any settings that I can configure in the security policy to prevent such entries?

Thank you.
