Unable to Bind TCP/IP to Dial-up Connections

I am running XP Home on my P4 laptop with all current
patches installed. My normal connection is wireless
802.11b through a router to a DSL modem. When I leave
home I am unable to establish connectivity using my modem
or LAN port. I have tried using the new connection wizard
and tried manually installing a new connection. In
either case, after setting up a new connection, I can
actually connect and be logged on to my ISP. However,
browser and email clients will not work. I suspect a
problem with name resolution, and dynamic IP addressing
with DHCP and TCP/IP not binding to the new connections.
Cannot ping any address except loopback. I have tried un-
installing my wireless connection to no avail.

I was advised by my laptop maker's (vpr Matrix) tech
support that I should re-install XP, but I see that as an
undesireably complicated task. Does anyone know of a way
to fix this problem by tweaking registries?
 
It sounds like you have multiple connections to the Internet at one time
(wireless, and LAN). Depending on how your ISP issues IP addresses, it is
possible that you do not have an IP address for each of the interfaces on
your machine.

If you open a command prompt and type "ipconfig /all" this will show you if
you have an IP address for each interface.

It's unfortunate the customer support folks have told you to re-install XP
since that is quite a bit of overkill. If you can re-produce your problem,
paste in the results of "ipconfig /all" here and I can take a look.

When both wireless and modem connections are active,
ipconfig reports different ip address, subnet mask and
DNS servers for each connection. However, ipconfig
reports the modem connection dhcp is not enabled, and
NetBios over TCPIP is disabled. I get the same ipconfig
dial-up report (no dhcp or NetBios) when I disable or
remove the wireless connection. I have already tried to
manually enable NetBios with no effect. Also tried
killing the firewall with no effect. After disconnecting
the dial-up, wireless connection will no longer work.
Rebooting gives the error message: tcpip network
transport not installed. Had to restore system to
earlier date to regain tcpip functionality on wireless
connection.
 
I have a similar problem on my son's machine only I only
only a dial up connection. The problem occurred imediatly
after installing the XP "worm" patch. I can establish a
connection to my ISP and log on, but when I try to browse
the web it tells me it cannot find the server. Other
programs, such as Symantec "Live update" cannot connect.

I would appreciate any help on this.
