       TEKINSIGHT.COM ANNOUNCES AVAILABILITY OF BUGSOLVER (TM) TEKSUPPORT

        BugSolver's Unique Streaming XML(TM)Technology Allows Value-added
           Resellers to Offer Support to Users When a Failure Occurs

NEW YORK -MAY 23, 2000 - TekInsight.com, Inc. (NASDAQ: TEKS TEKSW), an Internet
development company that offers software and services based on its Streaming
XML(TM) technology, today announced the availability of BugSolver(TM) TekSupport
for value-added resellers (VARs) and system integrators. BugSolver TekSupport
provides extensive, virtually instant, data on PCs and servers at the time of a
hardware or software failure. BugSolver TekSupport is the second in a series of
ASP-based BugSolver services.

BugSolver(TM) is an Internet-based application failure detection system that
resides on a client or server computer. It collects diagnostic data when a
program fails and forwards that information to a portal customized for the
VAR/integrator. BugSolver is activated automatically at the time of a crash and
collects information that will help identify the cause of the problem. BugSolver
TekSupport provides VARs and integrators with thirty times more statistical
information (more than 30,000 data points) on software problems, than the
operating system itself. This greatly improves user satisfaction and service
provider efficiency. When a crash occurs, the VAR/integrator will automatically
receive an email informing him that one of the computers he supports has failed.
It will then detail the failure and offer possible explanations.

BugSolver TekSupport's services include:

o        E-MAIL RESOLUTION: When a crash occurs, the VAR/integrator will
         automatically receive an email informing him that one of the computers
         he supports has failed. It will then detail the failure and offer
         possible explanations.
o        MIGRATION ANALYSIS: Collects data needed to test whether a client's
         migration to a new operating system or network server will go smoothly
         or changes are in order before full implementation.
o        INTERNAL GROUP REPORTS: Collects thousands of fields of data that
         enables the client to create internal system configuration and
         utilization reports.
o        INDUSTRY TREND REPORTS: Provides specific industry reports, compiles
         and maintains crash data and analysis information from its extensive
         and diverse



         client pool, and provides VARs with large-scale analysis of the PC
         computing universe.
o        ASSET MANAGEMENT: Allows VARs and their clients to collect and maintain
         updated asset records by taking a detailed system "snap-shot" and
         transmitting it to a central repository. VARs are able to quickly
         compare and contrast the client's system to identify the source of a
         hardware conflict.

"With BugSolver TekSupport, resellers will now be able to offer their customers
an exceptional level of support," said Alexander Kalpaxis, Chairman and CTO of
TekInsight.com. "By installing BugSolver on customer desktops, a reseller will
be able to diagnose system failures remotely, while proactively addressing
conflicts and reducing the time needed to determine what causes a system crash
by up to 80 percent. BugSolver TekSupport greatly reduces load and costs
associated with operating technical support."

At the heart of BugSolver is a unique technology called Streaming XML(TM) that
gives VARs control over their client base, regardless of size. Developed by
TekInsight.com, Streaming XML harnesses tremendous amounts of Internet and
PC-based data by streaming it into XML and compressing the format for real-time
storage and presentation. Streaming XML compresses the PC failure data and sends
it directly to the VAR for diagnosis.

Streaming XML enables BugSolver to supply the VAR/integrator with the crash
information that makes it possible for the VAR to analyze data relating to all
aspects of the client's networks and systems. By using BugSolver TekSupport, the
VAR can simply review the operational profile on the Internet to fix the problem
in a timely manner instead of spending a large amount of time on the telephone
or in person with the user during a failure,

"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 TekSupport 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."

More information on how to obtain BugSolver services is available on the
BugSolver Web site, www.bugsolver.com, or via e-mail to sales@bugsolver.com.
