Sun Microsystems Inc on Monday said it would cut the price of its Web server software by 37 percent in a bid to take market share away from Microsoft Corp.'s competing software. Palo Alto, California-based Sun said it would cut the price of its iPlanet Web Server Enterprise Edition 6.0 to $940 per computer processor from $1,495 for any customer changing from a competing platform. Sun said it would also make available software that would allow users to run pages written for Microsoft's server software format on that company's Internet Information Services (IIS) architecture on Sun's platform without modification. ``This program represents a cost-effective alternative for companies concerned about frequent Microsoft IIS security warnings, including Code Red and Nimda, and want to move to a more secure alternative without disrupting their business,'' Sun said in a statement. Last week Microsoft announced an initiative to make IIS more secure after a string of high-profile computer viruses exploited known problems with the software. Shares in Sun were down 8 cents at $9.79 in morning trade on Nasdaq.
