most important questions you will consider. If you have too much logging, the perfor-mance of your server and the network will decline sharply. If you have too little logging,when you have a problem, you won’t have the information you need to determine thesource and cause.The best choice is to log only those options you really need, and whenyou don’t need a particular type of log data anymore, stop recording it.In order to set the logging levels, open the RRAS module, right-click the server youwish to administer, choose Properties,and then click the Loggingtab. As shown inFigure 4.47, the Loggingtab contains several options for the various types of events thatyou can log.The default is to log all errors and warnings.You can also check the Logadditional Routing and Remote Access information (used for debugging)checkbox, which, as its name implies, will assist you in debugging.
