Can't connect to the internet

[Guest]

Hello Everyone

Laptop XP pro SP2

This laptop has no connection problem in a different network (different
organisation). But in our network, it refuses to connect to the internet.
However, it has no problem in relation to the intrAnet. It picks up the IP
address from the DHCP server with the correct DNS server; it pings google but
refuses to browse it.

Can anyone tell me the steps I should take to solve this ?

Many thanks

Best

To add another detail:

IE seems 'fine' as there is equally no connection to the internet using
Mozarila.

Thanks

Hi,
Sounds like a tricky situation. First I would suggest that you try resetting
the winsock.


1.. Click Start / Run, type cmd
2.. Run the following commands:
. Netsh int ip reset reset.log
.. Netsh winsock reset



3.. Restart your computer
Because sometime happens that this does not help, you can also manually
remove the winsock registry keys.



1.. Click Start / Run, type regedit
2.. Delete the following registry keys:
a.. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock
b.. HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Winsock2
3.. Restart the computer
4.. Open Network Connections
5.. Right click LAN connection and choose Properties
6.. Click Install, then Protocol and click Add
7.. Click I have Disk and type C:\WINDOWS\inf
8.. On the list choose Internet Protocol (TCP/IP) and click OK
9.. Restart your computer
You can also try to run computer in Safe Mode With Networking (press F8
while computer in starting up on choose option mentioned above). Another
options is running it in selective mode. To run the computer in selective
mode do the following steps:



1.. Click Start / Run, type msconfig
2.. On the General tab click to choose Selective Startup
3.. Clear Load Startup Items
4.. On Services tab click to choose Hide all Microsoft services
5.. Click Disable All
6.. Click OK and Restart
Locate the "Hosts" file and rename it. The file is in the folder
C:\WINDOWS\system32\drivers\etc.



Can you open web sites using their IP address? Does this problem persist in
other user accounts on this computer? What happens in selective mode and
safe mode with networking?



Regards,

Hello Vicent and Anton

I ran the Network Diagnostics on the laptop. Everything passed except the
IEProxy. It failed. However, this failure does not seem to be related to
the Proxy settings because I checked them against different machines which
are configured in the same way as the laptop. The pinging of the Proxy
server does not only fail with this laptop but also with some other laptops.
I was told that it is within the DMZ.

Pinging www.google.com is fine.

The intersting bit is that when I accessed the laptop in Safe Mode with
Networking, both the intrAnet and the internet worked. I ran from the Safe
Mode with Networking the Network Diagnostics and it returned the same output
as it returned it in Normal Mode, i.e. everything passed except the Proxy.

If the problem was with the drivers, how can I go on about the elimination
process ? If something else, please advise.

For your info: using "msconfig", there are only three programs at the
Startup tab. I disabled them for testing and it made no difference.

Many thanks

Best

I notieced that you have performed some steps like clean boot. Pleae check
following steps:

1. Click Start, click Run, type "msconfig" (without the quotation marks) in
the Open box, and then click OK.
2. In the Startup tab, click the "Disable All" button.
3. In the Services tab, check the "Hide All Microsoft Services" checkbox,
and then click the "Disable All" button.
4. Click OK and restart your computer.

Hi,

If it work fine in Safe Mode with Networking there must be a services or
program conflict. Does the problem persist if you disable all startup
programs and non-microsoft services? Try the diagnostic startup in system
configuration utility to see if there is a conflict between Microsoft
services. Is there a possibility to bypass the proxy to see if it works
without it?

Hi Best,

Exactly, As Anton said.

It appears to be the services conflicts. Try the diagnostic startup should
be a opition. Please me know the results.

Have a good day.
