Hello,

This problem started a few days ago and ramped up yesterday and today. Yesterday I lost connection 7 times and I'm already at 4 for today. I checked my event viewer and keep seeing:

DHCP 1002

The IP address lease 192.168.1.64 for the Network Card with network address 001302243F5A has been denied by the DHCP server 192.168.1.254 (The DHCP Server sent a DHCPNACK message).


DHCP 1003
Your computer was not able to renew its address from the network (from the DHCP Server) for the Network Card with network address 001302243F5A. The following error occurred:
The operation was canceled by the user. . Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

For more information, see Help and Support Center at http://go.microsoft....ink/events.asp.

also TCPIP 4226
TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.

For more information, see Help and Support Center at http://go.microsoft....fwlink/events.a


this is happening on all three computers on the network. Any help would be much appreciated, I have a class online this week and don't want to be disconnected in the midst of it.

Thank you,
Lisa

Hi Leesie

Try flushing the DNS Cache and see if that helps "how to" below;

1.Press Windows+R to bring up the Run dialog box.
2.Type cmd then press ok.
3.In the command prompt that comes up enter ipconfig /flushdns then press return and your done.
Let us know how you get on.

Thanks Philipower2. Is it best to do that the next time it disconnects or can I do that at anytime?

Thanks,
Lisa

You are welcome :thumbsup:
Hopefully this will resolve the issue but if not checking your AV and firewall can be done next.

Well it's still acting up. 3x tonight.

The new error code is DCHP 1007 and TCPIP 4226.

I did the dns release and it helped once. If I do the /release and /renew and reboot I can get it back, but the last one lasted just twenty minutes before it acted up again.

Try WinSock XP Fix (it`s free) http://www.snapfiles...nsockxpfix.html

I am only suggesting the free download and in no way suggesting that you use any other product or service at the link.

Hi,

Back again. It's acted up twice tonight. TCPIP - 4226 both times.

Ran the winsock after the first one and it lasted another 4 hours before it happened again, then I rebooted and it went right back out.

Hi phillpower2 & Lisa
If you can't get this fixed by the time you need to logon to your class may I suggest that you go to a static ip address and see if it is stable for your lessons.
Since 2 computers are having the same problem have you rebooted the router (just an idea)
Have you checked the ip address on both machines could be a conflict.

Cheers

Hi Peter,

I've rebooted the router several times. Done the reset on it as well and the issue still persists. How would I go about trying a static IP address? I'm not very knowledgeable on that stuff. To check the ip addresses for conflict would that just be going into cmd and ipconfig /all?

Thanks,
Lisa
