Error message (The TCP/IP network transport is not installed)


L

Lim Boon Kwong

I ran the antispyware, it detected some files that are at
risk, I deleted them and re-start the laptop. An error
message "The TCP/IP network transport is not installed"
appears and now I am unable to connect to the internet.

I uninstalled the antispyware, it did not help.

I tried to uninstall the "internet protocol (TCP/IP)" at
properties of My Network Places so that I can re-install
it, the uninstall button is not active.

Please help!

Hi Lim Boon Kwong - Download both a copy of LSPFIX here:

The process of removing certain malware may kill your internet connection.
If this should occur, these programs, LSPFIX and WINSOCKFIX, will enable you
to regain your connection.

NOTE: It is reported that in XP SP2, the Run command netsh winsock reset
will fix this problem without the need for these programs. (You can also
try this if you're on XP SP1. There has also been one, as yet unconfirmed,
report that this also works there.) Also, one MS technician suggested the
following sequence:

netsh int reset all
ipconfig /flushdns

See also: http://windowsxp.mvps.org/winsock.htm for additional XPSP2
info/approaches using the netsh command.

recovering from a really really dead TCP/IP stack

REALLY REINSTALLING TCP/IP
Complete destruction and restoration of dead TCP/IP stack
Recovery from fatal failure or partial or complete corruption of TCP/IP.
For virus related problems, please consult tcpip.sys to ensure it is not a corrupt version before following these steps.

This solution is an alternative to reinstalling by partial method or by using winnt /unattend which I very much wanted to avoid.

Here is the hardcore method when nothing else is working. I have cobbled together these suggestions through various forums to offer them here as a concise solution. There are no guarantees! Back up anything relevant and set a system restore point to cover your ass. I discovered this method after all other solutions failed.

non-full reinstall of TCP/IP using only the have disk method. >>> no effect
netsh Winsock reset >>> no effect
http://www.snapfiles.com/get/winsockxpfix.html >>> no effect
reinstalling network card >>> no effect

MY SOLUTION:::

Step #1
Full uninstall of TCP/IP ... no bull****.
----------------------------------------------------------------------
These steps are copied from http://support.microsoft.com/kb/325356
11. Locate the Nettcpip.inf file in %winroot%\inf, and then open the file in Notepad.
12. Locate the [MS_TCPIP.PrimaryInstall] section.
13. Edit the Characteristics = 0xa0 entry and replace 0xa0 with 0x80.
14. Save the file, and then exit Notepad.
15. In Control Panel, double-click Network Connections, right-click Local Area Connection, and then select Properties.
16. On the General tab, click Install, select Protocol, and then click Add.
17. In the Select Network Protocols window, click Have Disk.
18. In the Copy manufacturer's files from: text box, type c:\windows\inf, and then click OK.
19. Select Internet Protocol (TCP/IP), and then click OK.
Note This step will return you to the Local Area Connection Properties screen, but now the Uninstall button is available.
20. Select Internet Protocol (TCP/IP), click Uninstall, and then click Yes.
RESTART

succesfull uninstallation of TCP/IP will remove numerous keys from the registry including
HKLM/system/CurrentControlSet/services/tcpip
HKLM/system/CurrentControlSet/services/dhcp
HKLM/system/CurrentControlSet/services/dnscache
HKLM/system/CurrentControlSet/services/ipsec
HKLM/system/CurrentControlSet/services/policyagent
HKLM/system/CurrentControlSet/services/atmarpc
HKLM/system/CurrentControlSet/services/nla
These represent various interconnected and interdependant services.

For good measure you should delete the following keys before reinstalling TCP/IP in step #2
HKLM/system/CurrentControlSet/services/winsock
HKLM/system/CurrentControlSet/services/winsock2

Step #2
Reinstall of TCP/IP
----------------------------------------------------------------------
Following the above substep #13, replace the 0x80 back to 0xa0, this will eliminate the related "unsigned driver" error that was encountered during the uninstallation phase.

Return to "local area connection"> properties > general tab > install > Protocol > TCP/IP

You may receive an "Extended Error" failure upon trying to reinstall the TCP/IP, this is related to the installer sub-system conflicting with the security database status.

to check the integrity of the security database
esentutl /g c:\windows\security\Database\secedit.sdb

There may be a message saying database is out of date
first try the recovery option
esentutl /r c:\windows\security\Database\secedit.sdb

this did not work for me, I needed the repair option
esentutl /p c:\windows\security\Database\secedit.sdb

rerun the /g option to ensure that integrity is good and database is up to date.

Now return to the "local area network setup"
choose install > protocol > tcp/ip and try again

reboot.
worked for me.

Jim,

I had the same issue while i was trying to remove the malaware Antivirus. Once I removed it i couldnt use the internet. I was on XP/SP2. The simple Run command 'netsh winsock reset' fixed the issue. I didnt need to do anything else!

I thought i will post it as was so very useful to me!

Cheers, MSS
