WESTFORD, Mass., Jun 14, 2004 /PRNewswire-FirstCall via COMTEX/ -- NetScout Systems (Nasdaq: NTCT) today unveiled a new On-line Learning Center and MasterCare(TM) Service Portal with improved access to training, support and knowledge resources for NetScout customers. The On-line Learning Center complements NetScout's full offering of on-site and regional training courses with new, on-line, on-demand learning modules that familiarize users with nGenius(R) Solution product features and problem-solving capabilities. The On-line Learning Center is free of charge to customers who have MasterCare support, providing direct access to learning tools for all IT staff members, at any time. The On-line Learning Center also offers a cost benefit to enterprises that have a large number of users to train, but face limited time and travel funding.

The first modules offered are a combination of interactive, multimedia and webcast "how-to" exercises that range from setting up and configuring response-time analysis for custom applications to using nGenius(R) Power Alarms and generating nGenius(R) Reports. In addition, the On-line Learning Center contains product demonstrations on key features of the nGenius Solution. NetScout will add new modules to the center on a regular basis.

"NetScout's new MasterCare Portal and On-line Learning Center are the latest examples of our dedication to continuously expand the quality and extent of support that we offer our customers," said Glenn Crossman, associate vice president of product management for NetScout Systems.
