The domain controller's security event logs are limited to 20 mb in size. Our DCs are so busy that a 20 mb log holds only a day worth of logs. I want to increase the size of the security log to a size which will hold at least 5 - 10 days of events, guessing it would be about 100 - 200 MB in size.
Will increasing the security event log size cause a performance issue?
Are there other considerations for sizing the security event log?
Could use advise how to best optimize the domain controller's event logs.
