Tech Tip: Locate unwanted media files/Support RADIUS servers with IAS

Windows 2000 Professional: Locate unwanted media files

Most companies have policies against downloading video clips and other multimedia files that aren't related to business because those files can quickly eat up available disk storage and bandwidth. Perhaps more importantly, some downloads can leave the company open to embarrassment and litigation.

Policing the network for unauthorized downloads can be difficult. One solution is to block certain file types at the firewall or SMTP gateway. Or you can locate offending files with a simple search using the Windows Search utility.

Another approach is to regularly scan servers and workstations for mpg, mpeg, jpg, and jpeg files, among others. ThumbsPlus from Cerious Software, although not designed specifically as a compliance monitoring tool, can help you scan the system to locate and view graphics files.

When you're scanning your Windows 2000 computers for unwanted media files, don't be too aggressive. If the images reside under the \Program Files folder, they're likely required by an application. Likewise, files in the Windows folder and its subfolders are generally used by Windows and shouldn't be deleted.

Windows 2000 Server: Support RADIUS servers with IAS

Remote Authentication Dial-In User Service (RADIUS) is a common authentication mechanism for remote users. It provides authentication services, as well as logon time accounting and other data. Adding RADIUS support to your network can simplify remote access administration.

Windows 2000 has its own RADIUS capability via the Internet Authentication Service (IAS). Setup doesn't install IAS by default, but you can add it by running Add/Remove Programs in Control Panel. You'll find IAS in the Network Services group in the Windows Components Wizard.

IAS provides integration between devices that require RADIUS and Windows accounts, which can greatly simplify configuration of dial-up equipment. For example, you might install a dial-up network access server (NAS) to allow a number of remote users to dial in to the network from home. Rather than perform authentication within the NAS, you can configure it to point to your Windows 2000 IAS server, which will authenticate dial-up users from their existing Windows accounts.

The primary benefit of using IAS is that you don't need to maintain two sets of user accounts (one for Windows authentication and another for remote authentication). Consolidating all authentications within a single set of accounts can considerably reduce administrative overhead.

IAS is the ticket if you need quick and easy RADIUS. If you need to closely track user logon time, however, look into a third-party RADIUS server application.
