RE: Very unusual network problem

Hello,

Thank you for posting here.

>From your post, I don't make sense of your issue very much. So before we go
further, please let me know following information so that we can perform
further research.
1. What's the exact meaning of "network crash"? Is there any error message?
You may send me a screen shot to show it:
To take a screen shot:
---------------------
1) Press the Pr Scrn key once on the keyboard when the error message
appears.
2) Click Start, go to Run, enter MSPAINT in the open dialog box, and then
Click OK.
3) Use Ctrl + V to paste the screenshot to the canvas.
4) From the File menu, go to Save and save it as a JPG file.
5) Send the JPG file to me as an attachment.

2. As you mentioned it crashed when you move file from Desktop to Laptop,
how about when you move file from Laptop to Desktop?

3. As you mentioned it was ok when you just checking mail which you called
it "small", how about when you move a 5M file?

4. This issue happens just recently?

For your situation, I'd like to provide you some general suggestions to
narrow down your issue:

Suggestion 1:
===============
Since you mentioned your motherboard firewire port with it, so please
disable it to see if your network still crashes. About how to disable the
firewire port please refer to your motherboard manual.

Suggestion 2:
===============
You may start your computer in safe mode to see if this issue occurs. And
the step to boot into safe mode is below:

Safe Mode loads a minimally protected-mode configuration, disabling Windows
device drivers and using the standard VGA display adapter.

1. Restart the computer.
2. Keep pressing F8 key until the Windows Startup menu appears.
3. Choose the Safe Mode with Network, and press Enter.

Note: Some third party applications and some hardware device cannot be used
during Safe Mode. You will temporarily be unable to connect to the Internet
temporarily while in Safe Mode.

If this issue disappears in the safe mode, I suspect that it is related to
some third-party services or programs. You may Use Clean Boot to eliminate
third party interference Boot into Clean Boot environment. Steps are below.

1. Click Start, click Run, type "msconfig" (without the quotation marks) in
the Open box, and then click OK.

2. In the Startup tab, click the "Disable All" button.

3. In the Services tab, check the "Hide All Microsoft Services" checkbox,
and then click the "Disable All" button.

4. Click OK and restart your computer.

Suggestion 3:
==========================
As you mentioned you have tried to use a program to completely delete the
TCP/IP settings, so I'd like to provide you a method to reset Tcp/Ip with a
command, you may also have a try:
1. Click "Start", click "Run", type "cmd" (without the quotation marks),
and then press ENTER.
2. Type the following command, and then press ENTER:"netsh int ip reset
log.txt" (without the quotation marks)
- If you incorrectly type the command, you receive an error message.
Type the command again.
- If the command successfully runs, a new command prompt appears.
3. Type the following command, and then press ENTER: "netsh winsock
reset" (without the quotation marks)
- If you incorrectly type the command, you receive an error message.
Type the command again.
- If the command successfully runs, a new command prompt appears.
4. Type "exit" (without the quotation marks), and then press ENTER.
5. Restart the computer.

Suggestion 4:
=======================
If your issue happens just recently, you may try to perform a system
restore to be back to the initial status or other correct state.

Note: if you have some important documents or files which are created after
the restore point, please copy them to My Document. As this, even if you
are back to the initial status, they are still remained in My Documents.

To restore your system to a previous state, we can use the following steps:

1. Before you start, please close all open files and close all open
programs.
2. Click "Start"; Click "Programs or All Programs"; Click "Accessories";
Click "System Tools"; Click "System Restore". The System Restore user
interface should appear.
3. Select "Restore my computer to an earlier time" and click "Next".
4. From the restore points available, select an appropriate restore point
when your system is working correctly and click "Next".
5. Click "Next" again. The restore process will run and your system will
restart automatically.
6. After restarting, check whether your system functions correctly now. If
not, you can undo your last restoration or select another restore point in
System Restore user interface.

| Hello
|
| I have 1 desktop and 1 laptop computer networked using XP PRO SP2 up to
date.
|
| They are both connected to an AP that also does DSL modem and network
switch (great stuff btw)
|
| The funny thing is that on the "big" computer the network goes down
during "big" transfers, for example if I try to move a 50 megs file from
the desktop to the laptop (or the other way around) the network crashes
randomly during the transfer, sometimes immediatly (10-15 seconds),
sometimes it stays up und running until 2-3 minutes but it always crashes.
|
| I have tried direct cross cable between desktop and laptop, or through
the switch and it still crashes the same, if I try to do "small" networking
like just checking the mail every 5 minutes on the big computer it works
for hours, so it's ONLY on BIG transfers that the crashes occurs.
|
| I have removed firewall, antivirus, ran all possible checks including
online scans, checked for spyware using spybot, spysweeper and ad aware and
of course there is NOTHING (I would have been glad to find something but I
didn't).
|
| Where the problem really gets funny is that my motherboard also has a
firewire port so I tried networking through the firewire, disabling the
"normal" network card and the problem is the same, so it is NOT the network
drivers or settings, QoS is LONG gone from my systems and i don't know what
to do.
|
| I have tried using a program to completely delete the TCP/IP settings and
resetting the LSP's but the problem is still the same.
|
| Thanks for the help, but please refrain from the usual virus-spyware and
so on, you would be wasting your time (and mine but it's not that bad, ha
ha ha)
