Hi SJ,
Thank you for your kind update.
Also, many thanks for Jim's great input.
Considering the current condition, please kindly perform the following
steps to isolate this issue:
1. Use the Ping or PathPing command-line tools to test basic connectivity.
Use Ping to isolate network hardware problems and incompatible
configurations. Use PathPing to detect packet loss over multiple-hop trips.
To watch Ping statistics, use the ping -t command. To see statistics and
continue, press CTRL+BREAK. To stop, press CTRL+C. If you detect lost
packets in the statistics output, this indicates networking problems up to
Open Systems Interconnection (OSI) layer 3 (IP-level connectivity).
2. Check the event logs for network-card-related entries or
connectivity-related entries.
For additional information, click the following article number to view the
article in the Microsoft Knowledge Base:
308427 (http://support.microsoft.com/kb/308427/) HOW TO: View and manage
event logs in Event Viewer in Windows XP
3. Check whether the network adapter is on the Microsoft Hardware
Compatibility List (HCL). To see the HCL, visit the following Microsoft Web
site:
Hardware Driver Quality (http://www.microsoft.com/hcl/default.asp)
4. Check other computers that use the same default gateway that are plugged
into the same hub or switch. If these computers do not experience network
connectivity problems, the problem may be a faulty network adapter on one
computer.
If this is the case, update the network adapter driver to the latest
version.
5. Contact the vendor of each motherboard and update the BIOS of the
boards. Some network adapters and motherboards or BIOS versions are
incompatible. Obtain the latest version from the vendor's Web site or
contact your hardware vendor.
6. Check the network adapter and uplink hardware (hub or switch) for common
settings. Make sure that all complementing network resources (network
adapter, hub, and switch) are set to the same speed and duplex level. If
the media type is set to autosense, autosensing, or autodetect, or "Auto
Select," make sure that all components are autosensing correctly.
On some switches, a duplex setting of Auto may cause it to use half-duplex.
You may have to force it to use full-duplex.
Reset the switch, restart the client, and test the connectivity.
Put the client and the server on a passive hub. If communication resumes,
the problem may be caused by an incorrect network switch configuration.
For more information about how to configure the devices, contact your
hardware vendor.
7. Manually set the network adapter of the computer that has connectivity
problems to half-duplex and a lower speed.
Connect the system to a switch that is configured to half-duplex and
10-Mbps, or use a 10-Mbps hub, to see if connection can be established at a
lower transmission speed.
To increase performance, increase the speed settings manually to 100 Mbps,
and then restart the computers. Test for network connectivity loss,
increase the setting to full-duplex, and then restart the computers. If
network loss occurs, reduce the duplex setting and the speed to the
previous settings.
8. Swap the network cable between the failing system and the hub or switch.
9. Replace the network adapter with a network adapter that has been tested
and proven reliable. To do this, follow these steps: a. Remove the network
adapter diagnostics program.
b. Remove the network adapter in Network properties.
c. Install the new network adapter.
I appreciate your time and cooperation. Please do not hesitate to let me
know if you have any further concerns, I am looking forward to hearing from
you.
Best regards,
Nathan Liu (MSFT)
