I have a windows xp pc with service pack 1a. I recently
loaded a modem and its corresponding software. I can dial
and connect to my service provider. when I check the
adapter properties I seem to be sending packets out but
not getting any back.
I have removed any filter and firewalls on the system.
I have also tried using the ping command and I can ping
the out side world using an ip address (ie: gateway, dns
etc.. but I can not access any web pages. I have also
tried to use an ip address in the browser. still no
success.
One problem that is evident is that I can not aqquire a
dhcp address. not even with ipconfig /renew.
Is there a way to fix this without reloading XP.
THANKS FOR YOUR HELP IN ADVANCE.
=============================================
This is a Dial Up Connection?
Or is it PPPoE DSL?
If Dial Up -
When you run ipconfig /all in the command prompt window
and get the information for the PPP adapter that refers to your ISP
does it say that DHCP is enabled?
Are you getting an IP Address for the PPP adapter in the APIPA
form of 169.254.x.x? Or do you get a legitmate IP Address from
your ISP?
When you try ipconfig /renew do you get this error?
"The operation failed as no adapter is in the state permissable for
this operation"
Or do you get a different error?
If this is PPPoE DSL -
When you run ipconfig /all do you get an APIPA type 169.254.x.x
or do you get a legitimate IP Address?
When you try ipconfig /renew do you get this error?
"An operation was attempted on something that is not a socket"
Or do you get a different error?
What firewalls / filters did you remove and how exactly did you remove
them?
If you have not already installed the Critical Update
WindowsXP-KB823980-x86-ENU.exe
you better enable the XP built in ICF on your connection before
connecting to the Internet and then go straight to the Windows Update
Site and install all critical updates available or you may get hit by the
MSBLASTER worm.
From what you descibe, you may have damaged Winsock keys
in the registry.
You should check System Information (winmsd)
Expand Components / Network / click on Protocol -
if the section headings item of "Name" have a value
starting with with anything other than MSAFD or RSVP
then that is probably what is causing the problem.
Examples:
MSAFD Tcpip [TCP/IP]
MSAFD Tcpip [UDP/IP]
RSVP UDP Service Provider
RSVP TCP Service Provider
MSAFD NetBIOS [\Device\NetBT_Tcpip...
and so on
It may be a third-party firewall or a Spyware or a Virus.
("New.Net" is a common spyware for example)
Make sure that MSCONFIG is in Normal Startup
and then see if uninstalling the third party firewall
(best done from its own uninstall program if available)
or the Spyware from Add Remove Programs will
resolve the issue. If it's a virus, then only an Anti Virus Program
will be able to deal with that.
You may want to try downloading either Ad-Aware 6 or Spybot
to another computer and then installing one of them on the infected XP
Home/Pro
computer and try to wipe out Spyware and see if that resolves the issue.
Ad-aware 6.0 build 181
http://download.com.com/3000-2144-10214379.html?tag=list
Spybot - Search & Destroy 1.2

If none of that works or is possible, you could try this method
for replacing the winsock and winsock2 registry keys:
Uninstall any third-party proxy software or firewall programs before
proceeding.
Step 1: Delete registry keys
A)Open Regedit from the Run line
B)Go to both of the following keys, EXPORT each of them, and then delete
them:
(To export a key, you right click on it and choose "export" - you can choose
where to export them to -
DESKTOP is handy -
and you need to type in a file name such as "exported Winsock key" /
"exported WinSock2 key"
and then click on SAVE)
HKLM\SYSTEM\CurrentControlSet\Services\Winsock
HKLM\SYSTEM\CurrentControlSet\Services\WinSock2
C)Restart the computer
NOTE: It is important to restart the computer after deleting the Winsock
keys.
Doing so causes the XP operating system to recreate shell entries for those
two
keys. If this is not done, the next step does not work correctly.
Step 2: Install TCP/IP on top of itself
A)Open the properties window of the network connection (Local Area
Connection)
B)Click Install
C)Click Protocol, then Add
D)Click Have Disk
E)Type the path to the \%systemroot%\inf folder (usually C:\Windows\inf) and
click OK
(if you try to click Browse, then browse to the \inf folder,
it may not show up in the list)
F)You should now see "Internet Protocol (TCP/IP)" in the list of available
protocols. Select it and click OK.
G)Restart the computer
When the computer reboots you will have functional Winsock keys.
If so, then be sure to delete the exported winsock and winsock2 reg files.
(You don't want to accidentally put them back in the registry)
Side effects and possible problems:
This method will restore basic functionality to the Winsock keys, but is not
a
complete rebuild. On a default install of Windows XP the registry key:
HKLM\SYSTEM\CurrentControlSet\Services\Winsock2\
Parameters\Protocol_Catalog9\Catalog_Entries will have 11 sub-keys.
When applying this method, the Catalog_Entries will only have 3 sub-keys.
However, it works and there does not appear to be any side effects.
The missing entries relate back to the:
HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces key.
Also, third-party proxy software or firewalls may need to be reinstalled.
If issue is resolved, then be sure to delete the exported Winsock / WinSock2
..reg keys
as you don't want to accidentally end up importing those damaged keys back
into the registry.
