Hi
I'm using WIN Vista Home Premium Toshiba laptop.
My wireless service was not starting,after inquiry I came to know that WLAN AutoConfig is not running because one of its dependency service is not running too which is " NDIS Usermode I/O Protocol "
This service was showing Sign of Exclamation ( yellow) in device manager. I uninstalled it & Re-Scan it that might it will be fix but nothing happend.

I cannot find any solution over the net in any thread anywhere.
PLEASE HELP :(

Hello, a little research shows this : NDISUIO Implementation
Seems that you would be able to right click that driver in Device Manager and have it update driver and it would install it. Post back if you are able to get it this way or not. If not , there may be another way.

I already have done this. Inside report below is my problem.

C:\Windows\System32\drivers"\[l:22{11}]"ndisuio.sys"; source file in store is also corrupted.

I think this file/driver has corrupted which SFC command connot repair too.

Yes I have tried with Restore point to 3 days back, then even 9 days back but wireless adapter is not working.
What I'm going to try is to replace ndisuio.sys from a healthy computer to my computer, I will try to replace it during SAFE MODE.

Its DONE ~ My Wireless adapter started to work finally.

Let me summerize all this again for future readers.

My problem:
Wireless adapter was not running,hence couldn't connect to internet. This was because of WLan AutoConfig service was not getting started due to one of dependecny service " NDIS Usermode I/O Protocol " was unable to run. Infact one of system file (ndisuio.sys) got corrupted which causes "NDIS Usermode I/O Protocol " not to be run.

Solution:
Solution is only to replace " ndisuio.sys " into its directory " C:\Windows\System32\drivers\ " for ( WIN VISTA / WIN 7 )

Window doesn't allow to change/edit system files *.sys but YES, you can change/replace them.

HOW TO REPLACE SYSTEM FILES:
My system user account was real built in admin account. If you are getting in problem for this, you can enable it from here

http://www.vistax64.com/tutorials/67567-administrator-account.html

ndisuio.sys in your system is BAD/CORRUPTED, you first need to have the GOOD one. which you should take from vista/win7 Window installation CD/DVD. You can get a good copy of your corrupted file from here

http://www.vistax64.com/tutorials/261616-extract-files-vista-installation-dvd.html

Now you are system administrator & having good copy of your corrupted file, follow these procedure as,

1) Take ownership of " ndisuio.sys " file to edit/delete/replace it. You can do it with the help of this artical.

How to Delete a System File in Windows 7 or Vista - How-To Geek

2) Once you get the ownership of that file, rename the old file with any name and place the new one which you have extracted in above step from Window CD/DVD.

3) Go to device manager & find your wireless adapter entry under "Network adapters", Right click on it and click "Update Driver Software", it will prompt you a box, select "Brows my computer for driver software" then select "Let me pick from a list of device drivers on my computer"
It will show you available driver into your current system,select any latest and click Next button.

It will update your driver and meanwhile it will start your "NDIS Usermode I/O Protocol" service. You will see your wireless will start working same time If not, make sure WLan Autoconfig service is running in services.msc entries or START it by yourself.

This is how I solved my problem and hope it will be helpful for others but I can't gaurantee that it will work for you but you may try.

Thanks Yard Dog, Brink and this forum to help me in solving my problem. :cool:
