Trouble uninstalling KB826942

[Guest]

Hello to the XP gurus,


My wife's Christmas Win XP computer turned out to be quite a challenge and I don't know enough about XP to help her. Out of the box it worked nicely, it found the Internet and it talked over our wireless network. So she started by updating with the service packs, out to all but 5 of the recommended updates. Then she found that the updates had wiped out connectivity with the other three computers on the wireless network and the wireless access to the Internet disappeared.

Thanks to this group's discussions, we learned that the KB826942 update had installed WPA for a wireless network whose Access point doesn't support it. Hoping that uninstalling KB826942 would fix this, she started uninstall blindly. She began to panic when the uninstaller said "Setup cannot copy the file dhcpcsvc.dll" and asked her to find it or continue without replacing it. She chose to continue without finding the files and the warning occured six more times.

This imperfect uninstall did not correct the problem -- indeed, it cut her off from the network and the Internet. I assume that eliminating the critical network files caused this failure. I also suspect that running seven updates after KB826942 caused the confusion for the Win XP Uninstaller. Fortunately, the Restore function worked and took us back to a point after the updates, but with KB826942 still active. This leaves me in a real quandry as how to uninstall KB826942.

If the Win XP Unistall doesn't know which versions of dhcpcsvc.dll, ndis.sys, ndisuio.sys, netshell.dll, wzcdlg.dll, wzcsapi.dll, and wzcsvc.dll to restore, how am I supposed to be able to pick the correct ones? In the case of ndis.sys, netshell.dll and wzcdlg.dll, the only versions of these files left on the computer are the ones that came with KB826942. There are multiple verisions of the others on the computer. The version of ndisuio.sys that came with KB826942 is dated 2 August and the versions of wzcsapi.dll and wzcsvc.dll are dated 6 October. The ones identified in the SP1.cab are dated 29 Aug and the original 17 August dlls are still in DRIVER.CAB. I tend to believe I should restore the SP1 versions where they exist, but I don't know what to do about ndis.sys, netshell.dll and wzcdlg.dll.

Does anyone have any advice? Thanks in advance if you can help.

This "update" also broke my wireless connection - well
done Windows Update!! (not!)

Anyway, liek you, I also tried uninstalling it, with poor
results.

What worked for me - untick "Use Windows to configure
Wireless Networks" in the "advanced" tab when for the
wireless networks

Hopefully then the application / driver software of your
wireless card will then take over. (In my case the
Netgear software took over)

Thanks Shane,


I'm taking your advice. Although I cannot install WEP codes through my wireless card driver, I suspect I can safely run without WEP for a while.

I also think you've resolved my worries about ndis.sys etc. If these come from the XP system, I can restore, again, and be no worse off. And if they come from my wireless card, I can reinstall it. Either way I am better off than I am now.

I think that Microsoft should have anticipated that some of us would want to turn off WPA, but not WEP and made that a simple option.


Thanks again and best regards,
