[gs06]

I'm trying to connect with my ThinkPad (windows XP pro) to a friend's network I was able to do it yesterday, but today not !
I made sure the newtork, wires all working fine.
Also, I disable the wireless connection, disable the network card / Intel® Pro/100 VE Network Connection > restarted > a new hardware was detected > still nothing.
I keep getting a message there is limited connection ...

Any ideas what i should do ?

Thanks for your help.

Please follow the rules. Your post has been edited.

Does your friend have DHCP running? Make sure you are set to obtain an IP address automatically.

Has anything changed (in your PC) after the last sucessfull connection?

Do you have XP fully patched? This is a known issue, however, Microsoft has released a fix to it many time ago. You may need to install it if you don't have it already.

Thank you Gouki for getting back to me.

That's the thing that drives me nuts no changes what so ever on the thinkpad..

"XP fully patched?" i do't know, how can i find out ?

Well, this may solve your problem.

First, you will need to download this patch from Microsoft's site.

Then ....

Open Notepad and paste this into it:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\IPSec]
"AssumeUDPEncapsulationContextOnSendRule"=dword:00000002

Select Save As

File Type: All Files

Name: gs06.reg

Now .. Start the patch installation, when it is installed, run the gs06.reg file and reboot your computer.

Microsoft has an article talking about this problem, however, they only mention access to Internet (cable and DSL).
