        TEKINSIGHT.COM ANNOUNCES AVAILABILITY OF BUGSOLVER (TM) DEVELOPER

Software Support Professionals Now Get 20 Times More Information From Crashed PC
        Instantly Through BugSolver's Unique Streaming XML(TM) Technology

NEW YORK APRIL 17, 2000 -TekInsight.Com, Inc. (NASDAQ: TEKS TEKSW) today
announced the availability of the company's first of several services, BugSolver
Developer(TM). BugSolver Developer helps software development personnel provide
virtually instant, accurate answers to desktop/mobile computer users when a
hardware or software failure occurs.

Through the use of a non-intrusive software agent that is resident on the user's
computer, BugSolver Developer generates an in-depth operational profile of the
PC at the time of failure. This data-rich profile is sent via the Internet to a
private area on the BugSolver Web site, which tracks each PC's crash history.
Rather than spending a great deal of time on the phone or in person with the
user, the BugSolver support professional simply reviews the operational profile
on the Web to fix the problem in a timely manner.

"One of the biggest problems the support industry faces is the gathering of
information from the end user or operating system failure codes," said Richard
Rysiewicz, Director of the Service Section of the Computing Technology Industry
Association (CompTIA). "This causes huge inefficiencies in technical support and
service industries. BugSolver Developer provides much more comprehensive data on
the PC's condition at the time of the problem. It has the potential to
dramatically reduce the cost and increase the speed of technical support,
improving the productivity of support organizations around the world."

At the heart of BugSolver is a unique technology called Streaming XML(TM).
Developed by TekInsight.com, Streaming XML harnesses today's tremendous amount
of Internet and PC-based data by streaming it into XML and compressing the
format for real-time storage and presentation.



"Our Streaming XML technology is allowing us to develop new and innovative
products like BugSolver," said Alex Kalpaxis, TekInsight.com chief technology
officer. "We are extending our core technology into large-scale e-commerce
initiatives to help our customers collect massive amounts of information from
multiple real-time sources and manage that flow of data. Streaming XML gives
scalability and control."

The Help Desk Institute, a computer services industry research group
(www.helpdeskinst.com), estimates that up to 80 percent of technical support
cost stems from the time it takes to uncover and re-enact activities at the time
of a software or hardware failure. BugSolver Developer reduces this time
significantly and generates more than 20 times the amount of failure information
regarding the condition of the computer at the time of failure, allowing for
more efficient problem-solving.

Initial users have found Bugsolver to improve their ability to support the
management of web sites from both a hardware and software perspective.
Infocrossing (www.infocrossing.com), a subsidiary of COSI (Nasdaq:COSI), a
premier provider of collocation services, complex managed web-hosting services
and other value-added e-commerce services to Application Service Providers
(ASPs), Internet Service Providers (ISPs) and web-oriented enterprises, is an
early adopter of BugSolver. Infocrossing supplies on-line, custom management
software tools, using BugSolver to support its mission-critical users.

"BugSolver allows our engineers to quickly identify major failures, which
quickly correct problems and prevents future failures," according to Joseph
Germanotta, Infocrossing President and COO. "We feel confident that this product
helps ensure the reliability and availability of our customers applications."

BugSolver Developer is the first in a series of BugSolver services aimed at
different types of users. The BugSolver Developer support service is available
by subscription to developer support organizations and third party technical
support providers. More information on how to obtain the service is available on
the BugSolver Web site, via e-mail to sales@bugsolver.com.
