The Basics |
What is
NetGong and why do I need it?
NetGong is an intuitive network monitoring tool that
allows network administrators, webmasters, and Internet
service providers to monitor any networked device on the
Internet, corporate intranet, or TCP/IP LAN and receive
alerts immediately via audible alarm, message, e-mail,
or third-party software when a connection fails. It is a
powerful personal monitoring product delivering low
cost, simplicity of operation, and round-the-clock
coverage.
Round-the-clock network availability is
mission-critical to any successful e-business. Without a
sophisticated monitoring solution, network devices or
services can fail without so much as a peep. If that
crash occurs over a holiday or weekend, you could be out
of business for hours, or possibly days. Worse yet, you
might find out from an irate customer. Avoid costly
network downtime by using NetGong as your first line of
defense. NetGong continually probes and transacts with
network resources on timed intervals, to test their
availability and responsiveness. If a failure occurs,
NetGong automatically notifies you. The result? You are
back in business faster!
What are the system
requirements for NetGong?
- Windows XP, Server 2003, Vista, Server 2008, 7,
and Server 2008 R2.
- Internet Explorer 6 or later.
Why did you rename IPMonitor to
NetGong?
We have formally renamed our network monitoring tool
to NetGong in order to reflect a new emphasis on event
notification technology and to better match the
company's product line.
How renaming will be effected on
users of IPMonitor?
There are no changes and IPMonitor 6.0 license key
will be working for NetGong 6.0 users equally.
Does NetGong have the same
features as IPMonitor?
NetGong 6.0 is fully compatible with IPMonitor 6.0
and includes all functions as well. IPMonitor was
formally renamed NetGong to reflect a new emphasis on
event notification technology and to better match the
company's product line.
I am the user of IPMonitor. Should
I upgrade to NetGong?
Yes, because there will be no further support for
IPMonitor. The upgrade is free of charge for users of
IPMonitor 6.0.
How can I save all my setting and
transfer them to NetGong?
NetGong has a function to restore user’s settings
from IPMonitor. All you need is to save all settings in
IPMonitor and restore them in NetGong.

Getting Started |
When I
try to start NetGong, I get an error message about a
missing OLEACC.DLL. What do I do?
This file is a component of Microsoft Active
Accessibility (MSAA) library. Probably you don't have
MSAA installed, or the installed version is outdated. To
resolve this problem, please do the following:
- Windows 98, Me, NT, and 2000. Download
and install the current MSAA version 2.0 from
Microsoft.
When I try to start
NetGong, it hangs at the information screen. What do I
do?
Probably Active scripting is disabled for your My
Computer security zone. This security zone is hidden by
default on the Security tab in the Internet Options
dialog box. The Flags value in the following registry
key determines whether you can view the My Computer
security zone on the Security tab in the Internet
Options dialog
box:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet
Settings\Zones\0
Setting the data value of the
Flags value to 47 (in hexadecimal) causes the My
Computer security zone to be displayed. Setting the data
value of the Flags value to 21 (in hexadecimal) causes
the My Computer security zone to be hidden.
To
enable NetGong to run, you need to enable Active
Scripting. Please do the following:
- Start Internet Explorer.
- Select Internet Options from the Tools menu.
- Select My Computer on the Security tab.
- Press the Custom Level button.
- Enable Active scripting.
When I start NetGong, for the
first few minutes, everything seems to work fine, but
then all hosts get stuck on verifying and eventually my
screen is flooded with messages saying host failed. What
do I do?
Test and change your connection's maximum
transmission unit (MTU) limit. An MTU limit that is set
too high can cause fragmented packets and packet loss on
your connection. This
tutorial will explain how to test if your MTU limit
is sending fragmented packets and will explain how to
find what value you should be using.
Why does my NetGong icon change
colors?
Whenever NetGong is running, its icon will be visible
in the system tray. However, apart from simply letting
you know whether or not NetGong is running, the icon is
also dynamic and will change colors based upon the
current NetGong status. The following is a list of the
icon indicators:
- Violet - All OK.
- Red - Network is down, no answer from host,
or service failed.
What is NetGong
service?
The NetGong service is a background process which is
loaded when the computer is started. This occurs before
you log in. If you launch NetGong on the desktop, the
service instance will terminate. When you exit NetGong
or logoff, it will initiate a startup of NetGong in the
current service context.
Why NetGong
service?
The NetGong service can be started without you having
to login to the computer. The service also will not stop
after you log off. The benefit of running NetGong as a
service is you can schedule your monitoring operations
and be sure that NetGong is running them when you are
logged in or not.

Common Questions |
What is a host?
Any (end-user) computer system that connected to a
network. Hosts range in size from personal computers to
supercomputers.
What is an IP
address?
The 32-bit address assigned to hosts that want to
participate in a TCP/IP Internet. IP addresses are the
abstraction of physical hardware addresses just as an
internet is an abstraction of physical networks.
Actually assigned to the interconnection of a host to a
physical network, an IP address consists of a network
portion and a host portion. The partition makes routing
efficient.
What is a port?
The abstraction that transport protocols use to
distinguish among multiple destinations within a given
host computer. TCP/IP protocols identify ports using
small positive integers. Usually, the operating system
allows an application program to specify which port it
wants to use. Some ports are reserved for standard
services (e.g. electronic mail).
What is IP?
(Internet Protocol) The TCP/IP standard
protocol that defines the IP datagram as the unit of
information passed across an internet and provides the
basis for connectionless, best-effort packet delivery
service. IP includes the ICMP control and error message
protocol as an integral part.
What is TCP?
(transmission Control Protocol) The TCP/IP
standard transport level protocol that provides the
reliable, full duplex, stream service on which many
application protocols depend. TCP allows a process on
one machine to send a stream of data to a process on
another. It is connection-oriented in the sense that
before transmitting data, participants must establish a
connection. Software implementing TCP usually resides in
the operating system and uses the IP protocol to
transmit information across the underlying internet.
What is UDP?
(User Datagram Protocol) The TCP/IP standard
protocol that allows an application program on one
machine to send a datagram to an application program on
another machine. UDP uses the Internet Protocol (IP) to
deliver datagrams. Conceptually, the important
difference between UDP datagrams and IP datagrams is
that UDP includes a protocol port number, allowing the
sender to distinguish among multiple destinations
(application programs) on the remote machine. In
practice, UDP also includes a checksum over the data
being sent.

What is
RTT?
(Round trip Time) A measure of delay between
two hosts. The round trip time consists of the total
time taken for a single packet or datagram to leave one
machine, reach the other and return. In most packet
switching network delays vary as a result of congestion.
Thus, measures of round trip times usually give
averages, which may have high standard deviation.
When I press the Refresh button, I
get an event log message with ID 4226. What do I
do?
By design Windows XP Service Pack 2 limits
the number of simultaneous incomplete outbound TCP
connection attempts to 10. After the rate is reached,
subsequent connection attempts are placed in a queue
eventually to be resolved at a fixed rate. This slows
down programs that open multiple TCP connections at
once. NetGong is a good example of this. If there are
more concurrent TCP connection attempts, Windows XP
Service Pack 2 generates a warning: "TCP/IP has reached
the security limit imposed on the number of concurrent
(incomplete) TCP connect attempts."
To change or remove the limit, you can use
a patching program. For more information please visit http://www.lvllord.de/.
