After windows update on 13 May 2008, I noticed that my connection to the
Internet had stopped working. After system reboot the problem persists.
The network diagnosis is stating that there is only local network
connection. It fails to repair the connection problem and the network map can
not be displayed.

My access to the Internet is via DSL modem, this operating properly as the
other PCs on my home network are connecting without any issues. These are
Windows XP systems.
I have encountered this problem before when Vista was booted with the DSL
router/modem switched off. The network diagnosis and repair has never worked
for (unlike Windows XP) to get the connection back required system restart.

This time it seems to be different multiple restarts have failed to correct
the coonection problem.
There is no problems or issues with the network or the DSL Router/modem. The
computer is operating coorectly and there are no hardware issues. (I am
sending this post for the Vista PC, now dual booted into Windows XP)

I am using Vista Ultimate SP1 with all upadtes as of 13 May 2008. Vista
installation has been operating without any serious issues since December
2007 until now!

Has anyone come across this problem?

Thanks!

Thank for the response!
The problem seems to have corrected itself after the PC rebooted. The DSL
modem was not the problem as other PCs on the network at the same time, this
issue was occouring to the Vista PC, were connecting to Internet . These PCs
are Win XP systems. All the PCs on my home network are using ethernet cabling
(no wireless been used).

The question that I would like to get an answer to is why the diagnose and
repair utlility in Vista never seems to work?

If I replicate the problem with a Windows XP system (DSL modem off when
Windows boots and no IP address is assigned) the repair utility in Win XP
always repairs the connection, gets an IP address and connection to Internet
is restored.

Is there fundamental differences between Vista and XP in the way that the
TCPIP protocol stacks are implement? Could this be the problem with Vista
connecting to Routers/DSL Modems that do not support IP V6?

this should clear you up.

Hope this helps

Thanks john_cena the infomation is helpful!
I just wonder if there are isues with the Network Diagnostics Framework
(NDF) in Vista? To me it seems that it has problems analyzing networking
fualts that are caused by Vista itself. Its diagnoses is always to blame the
hardware or the cabling?
The Network and Sharing Center has a nice front end and the network topology
overview is good for users, but is not much use if it is pointing the users
in the wrong direction when there is a problem. It seems to have a simplistic
approach to analyzing problems.
I worked with midrange servers for years that use only text/menu driven
interfaces and the network diagnostics on these servers will always point you
to cause of the problem be it OS, hardware, or cabling. I hope that Windows
Server 2008 is better?
