Windows XP SP2 and BT Voyager 2000 ADSL Router

[John_Greythorne]

I have an ADSL router (a BT Voyager 2000) and three
workstations on a home network. The workstations are
Windows XP Home SP1, Windows XP Professional SP1 and
MacOS X 10.3.5.

The ADSL router is the DHCP server. All three
workstations are configured to automatically receive
their IP addresses from the router and connect to the
Internet. A text book setup in other words.

I just installed SP2 on to the Windows XP Pro
workstation. Now at random intervals I "half lose" my
Internet connection on the SP2 workstation.

I say "half lose" because I can still ping sites on the
Internet by IP address but not by name. The SP2
workstation still has its IP address (192.168.1.2) and
gateway address (192.168.1.1). My instinct is that
Windows XP is blocking DNS traffic between itself and the
router, but nothing is appearing in the event log to
indicate that. I have had the Windows Firewall on/off
and disabled with no effect on the problem. The two
other workstations function perfectly and exhibit none of
this irritation.

If I run a "ipconfig /renew", everything works again for
another random interval, whereupon the same thing
happens. If I manually set the DNS server to
192.168.1.1, all is peachy and I can surf for hours
without the fault happening. This is the temporary
solution that I have put in place, but I am not
installing SP2 on the other workstation (or on the 20-odd
workstations at work which have a similar DHCP setup)
until I know what is going on.

I know there are a lot of posts on similar topics, but
this problem seems subtly different. I think it's a
problem with DNS, DHCP and SP2. Whether it's being
caused by SP2 or by the BT Voyager performing some
misdeed that SP2 objects to, I don't know.

I was wondering if anyone else has had this problem, or
if anyone else has any ideas for me to try out. Any help
would be greatly appreciated.

Many thanks in advance.

Having the EXACT same problem,

Difference is that i'm connecting using Wifi.

I rolled back SP2 and it still happened but seemed to be less often.

Never had this problem Pre installing SP2.

I was thinking it might be due to the WPA Update in SP2 that allows
windows to use WPA Encryption over WiFi.

Are you using Wifi or a normal Lan?

Anyone have any ideas?

Thanks

Glen

Hi,
I have the same problem too, it's a relief to know it's not me but
very annoying. I have a call logged with Microsoft so I will let you
know if I hear how to resolve this. Again no problem before SP2 and
the only way I could find was the ipconfig /renew although I already
had an IP address so don't really understand how that fixes it

I only have the normal LAN set up at the minute as I was trying to
troubleshoot this problem. I don't really want to add another
complication!

Will keep you updated
