Folder, Printer, and Share Management Within each policy, there are a number of configuration screens that are presented in the form of a wizard. The wizard collects the following information to create a policy: ■ Name of Policy ■ Disk space limit and Unit of measurement ■ Passive limit (If selected the limit will issue warnings but will not prevent access. ■ Alarm Threshold for severe and warning messages ■ Notification for severe and warning messages The notification field allows for the creation of a message to be sent to the eventlog of the server or via Netbios as a pop up on the client machine. It should be noted that Netbios is not supported in all customer environments and the pop up function may not be supported.The notification includes macro functionality and variable definitions for user custom messages. The help function (?) in the right hand corner of the UI provides an online guide to building these macro function messages under the topic "Directory Quota Alarm Notification." To modify any of these settings at a later time the properties button may be selected for a particular policy or quota. In addition, to policy settings for existing shares, default policies can be set in advance for new devices added to the system via the preferences button on the Directory Quota Page. File Screening File screening allows the administrator to limit or monitor files based on extension, for example disallow all .pst and .mp3 files. It should be noted that the filter is merely based on extensions and not the content of the files. Hence, if a file extension is renamed away from .mp3 for example to mpp, the filter software will allow the file to be stored. A complete online help guide in the WebUI is provided for file screening via the ? in the right hand corner of the UI. File screening is established in the policy settings. Screening groups contain a collection of authorized and un-authorized file extensions. Filters determine which folders to exclude. Alarms, similar to the actions when a quota threshold is exceeded, can be set up when an unauthorized file type is set up. File screening includes the following features: ■ Active and passive file screening on directories ■ Best practice file screening policies ■ Notification alarm when file screening policy is violated ■ Audit database containing screened files ■ Customized alarm messages ■ Alarm messages to the event log ■ Alarm messages to a user ■ Storage reports when alarm is activated and sent to intranet Web site ■ Custom script when alarm is activated ■ Real time monitoring of file screening activity NAS 4000s and 9000s Administration Guide 151
