FW: Internet connection problem (XP Home edition) with my PC at home

Ladies and Gentlemen,=20

(NB: I am writing from my professional office, and some of=20
the data below are approximative)

Since May 31, 2004 (or maybe 2-3 days before or after?) my=20
PC at home doesn't connect anymore to the Internet, which=20
our home receives via TV cable through the provider=20
Urbanet of Lausanne (see <http://www.urbanet.ch>)

Urbant's tehnician came to my home and checked his part of=20
the installation, which works (Modem brand: Teraillon).=20
This is confirmed by the fact that my wife's portable PC=20
does indeed communicate properly with Internet while=20
connected to our TV cable at home.

Through "ipconfig" in DOS mode on my (defaulting) PC, we=20
can see that the IP address stays at the Microsoft Default=20
Number (269.xx.etc) and does not convert into the=20
urbanet's sent signal (IP Number set in automatic mode).=20
This IP address can be changed manually but doesn't change=20
automatically.

A friend of mine who is a professional consultant in PC's=20
ran a number of tests on this PC without success. However,=20
he arrives to the following conclusions:
- The function "restaurer le PC =E0 une date=20
ant=E9rieure" (under "system tools" of Windows XP) doesn't=20
give any result, the answer to the request being =AB Aucune=20
restauration n'a pu =EAtre effectu=E9e" after the system has=20
tried this procedure for about 30 seconds (we tried this=20
at different recovery dates without any success).
- While connected to a LAN network, my PC is capable=20
to communicate with IP numbers but is incapable to=20
translate letter addresses (or DNS ? eg bluewin.ch) into=20
IP Number addresses (eg 080.xx.yy.etc). In other words,=20
while connected to specific IP numbers, my PC receives=20
packets of bits, but while connecting through letter (or=20
DNS ?) addresses, the PC receives no "bits" at all).
- We hence conclude that the LAN card of my PC=20
functions properly.
- There seems to be a problem with a file=20
called "SHDOCLC.DLL" (or something alike) in the=20
C:/windows/system32 directory.
- The problem could be related to a file in the=20
Microsoft Explorer program (probably version 6 ?).

Can you help me out with this problem, for which I=20
personnaly can't think of any solution ?

Thank you in advance, regards,
