Windows XP loses internet connectivity after 25 minutes

L

Larry Kahm

This is just weird. It started on Monday of this week. I lose my internet
connection on a Win XP machine after 25 minutes.

Here's the environment: DSL line comes in, goes to Linksys router. One
Ethernet cable goes to workstation Antec (runs Windows XP Pro). Another
Ethernet cable goes to server N3000 (runs Windows 2K server).

The Antec workstation loses connection within 25 minutes of startup. I've
tried everything - I updated the router's firmware, I've had the DSL line
reset, I've changed the physical ports and cables on the router. I even
removed BlackIce from the system - Nothing but a hard reboot works. BUT the
N3000 server does not lose its connection - which is how I got to post this.

Here are the ipconfig /all files (if that's any help):

If anyone has >>any<< information, I would really appreciate it - this issue
is causing me much too much grief. Imagine, having the expectation that you
could stay connected to the internet all day long... Who'd a thought!

Thats odd, I have exactly the same problem! Just happened over night! Every now and then, my computer would disconnect. I preformed a hard reboot and it'll reconnect. After fiddling around with the network properties, it won't reconnect now. Even with the system recovery. This is really odd indeed.

I too am fighting with the issue of partial Internet loss.

After 10-25 Minutes I can no longer browse the web, or download files from
websites. This started happening after I removed a virus from two systems,
one a WinXP Home and another Win98. For both systems, if I restart windows
(note, not having to reboot) then I can browse for another 10-25 mins. After
I loose the ability to browse I can still PING, run email, even the browsers
resolve host names, they just can not pull data.

After some watching, I >think< it might be a port crashing issue, yet I have
repaired Windows, the network drivers and card drivers to no avail. I have
tried Winsock repair tools, no luck.

Anyone out there have any clue what to try next???

Ok, I have fixed one of my pest systems... the Win98 unit, have not had a
chance to try this out on the WinXP unit

The flow of the repair was something like this.

1) Removed all networking options, then protocols and clients then Hardware,
including the dial up networking
2) Ran a Defrag and rebooted
3) Skipped the network card install
4) added in a Dial Up Networking with TCP/IP
5) Rebooted
6) Installed Network Card Driver and rebooted
7) Tested ok...
8) After testing, adjusted bindings to remove MS Network Client from TCP/IP.
Still tested great...

My only guess is that by installing the dial up only first it forced a
rebuild of some protocol setting that was not binding fully. ???

That may be good for you ...

But I don't have a modem in my Antec machine, and the NIC is built-in to the motherboard.

I did apply the latest Windows required updates today - and so far, it has improved my "up time" to
30 minutes.

There is no modem in the unit I fixed... Dial up networking was installed to
help hide the Microsoft Client holes from the internet.

You can install Dial up networking using any modem driver. I just pick
Standard on COM2. After Installing everything, you can then hook the MS
client to the DUN and NetBUI and not TCP/IP preventing a few hacks.

Google for winsockxpfix.exe, Lspfix.exe. Run both. The first fixes
corrupted winsock, fairly common in XP, and the second fixes layered
service protocol, removing protocols that get installed from a varietyof
sources that screw with XP. Run lspfix in basic mode: open it and
select finish (expand the screen if the finish button is hidden).

For anyone following this thread...

None of the suggestions worked. Nothing I was able to change (or revert back to) had any affect.

This week I don't have any problem with extended connectivity.

Something very strange was going on...

Hello All,
It is possible that the Windows 2000 Server have set the limit of time for
the user's connection. Go and check on the user profile. Hope it works out.

If you are running windws XP go to the control panel and rerun the
networking wizard. BTW, I hate the darn thing but it worked for me.

I had the same issue. It seemed the computer wasn't resolving the DNS
addresses (though I could ping my ISP's DNS server, so there was a
connection to the internet).

I resolved it by hardcoding the DNS entries in the TCPIP properties for
the LAN connection. Originally, they were 192.168.1.1 (router
address), I just changed them to the actual addresses the router was
using (logged into the router @ http:\\192.168.1.1 and looked up the
DNS entries it was using).
