supported by Cisco's favorable outlook issued late Thursday. The Dow industrials closed up 194.02 to 10,423.17, a 1.9% increase while the Nasdaq composite rose 4.01%, 73.83 points to 1,916.80. The S&P 500 rose 22.84 to 1,184.93. Network parts leader Cisco said it is continuing to see signs of stabilization in its business. The company also announced a wide reorganization of its business following sharp job cuts. Adding to the momentum was good news from networking software company Novell which beat quarterly estimates and offered a favorable outlook. But dealers said gains in Microsoft may have helped the market the most. The company announced the completion of its Windows XP development and said the new operating system is being shipped to manufacturers. The company's anti-trust troubles also re-surfaced after an appeals court assigned a new judge, Colleen Kollar-Kotelly, to address Microsoft's dominance of operating systems.
