Missing File Ndis.sys


On my windows xp professional ver 2002 service pack 3 the file " ndis.sys " is missing from the c:windowssystem32drivers folder. I have tried to copy the file from c:windowsservicepackfiles folder but this did not help, so i deleted the new file in safe mode. Is there any way to download the correct file from microsoft. I think an anti virus programme deleted the file on me. I think this missing file is causing all my network adapters to display the yellow triangle.

Unable To Boot - Ndis.sys Is Corrupt

I ran the upgrade about 6 months ago and my computer has run fine, until yesterday when windows failed to start as described. At first i got the same message in the startup repair and diagnosis log, but after several attempts to start, sometimes i get that same message, and other times i get , under "root cause found:" boot critical file c:windowssystem32driversdis.sys is corrupt
The rest remains the same. I am not running any other os. Any ideas out there on resolution?

Problem: Delay On Boot Due To Drivers Files: Ndproxy.sys, Srv.sys, And Vga.sys

Recently installed a fresh copy of windows 7 x86 and x64 in separate instances to see if the problem of a two minute period between the "windows is starting" screen and the desktop. Neither had a visible impact. I looked around online and found how to create a boot log. The following are the drivers/services that could not be installed during my startup:

4 instances of ndproxy. Svs
1 instance of vga.sys (hadn't installed video card driver yet)
1 instance of srv.sys

After installing the necessary drivers and with no alert from the device manager, the boot time is still roughly 2 minutes. Right now i am at a loss on what to do. For reference my avg startup time in xp was around 10 seconds from the windows logo. Any help would greatly be appreciated.

Fix Error 651 Problem With Raspppoe.sys File

I have error 651 problems. I have a gateway sx-2800-01 desktop. It came with windows vista premium and was later upgraded with a gateway disc to windows 7. I used an at&t dsl connection which worked fine. When i switched to my current time warner cable modem i have started receiving this error along with a dial up window which reads "dialing attempt 1 . Unable to establish a connection. I also get messages telling me the page i want is not available offline. These are all new problems.

I tried to rename file raspppoe.sys to raspppoe. Old as recommended and i get a window that tells me "file access denied" because i am not a "trusted installer". When i try to click on the link in part 2 of the fix. Shell. Windows.com/fileassoc/0409/xml/redir.asp?Ext=zip i got a web page not a download-able file. I tried searching the web and when i tried to download their fixes i got a high warning about the program. They seem like reputable sites. What can i do? Am i not understanding something about this problem? Why hasn't windows update fix this if microsoft is aware of the problem?

A Kernel File Is Missing From The Disk

Windows 7 installed perfectly. I have 2 hard drives. One 500gb which is my primary where windows 7 is installed. And another 160gb which was my old primary hard drive that contained win xp 32 bit. The 160gb hard drive was partitioned into 2 partitions and i wanted to merge those two and make it to one partition. But i had to format both partitions.

I formatted the second partition easily but the partition which had the windows xp didn't allow me to format it. So i used a gpart bootable disc and then formatted the two partitions again. That's where the problem started. After i restarted my computer, "a kernel file is missing from the disk. Insert a system diskette and restart the system. " Appeared. And i can't boot to windows 7 no matter what i do. I'm really desperate to make use of my windows 7 pc again.

Missing Inf File For Printer

I have recent;y set up my new win 7 pc, and re-installed my old printer ( which used to run on my old xp machine ), so far so good. Printer works on my new pc. I set up my old pc in another room for my daughter, and set up a home network. I have set the epson printer on my pc to share, and can see this printer from my old pc, through the network.

The problem comes when i try to set this printer as my default printer. On my old pc, it tells me that i do not have the required driver file on my server to connect to the shared printer, and prompts me for an inf file, which i understand is a windows information prompt file. How and where do i locate this file , so my old computer can print to the shared printer through the network? Any ideas?

Win 7 Upgrade Missing File

I am upgrading from windows xp home edition to windows 7 professional through the itsnotcheating offer to students. I have downloaded the .exe file twice and selected the run file when done check box as it was downloading. Unfortunately, an error dialogue box (i haven't recorded or screen captured the error message) appears when the download completes and runs the .exe file. It mentions something about a missing file (apparently there are 3 files needed to complete the installation). Has anyone had this experience and if so, how can it be resolved?

File Boot Bcd Missing 0xc000000d

When i try to boot, with the dvd drive empty, with windows7 home premium disk or the repair disk as per instructions, i receives an error message of: file:bootbcd missing. Status: 0xc000000d. Info: the windows boot configuration data file is missing required information. I loaded windows 7 with this same drive and initially everything was working correctly. Then this problem began, the drive is working with all of my other disk. Changed the the statup boot cycle to the hard-drive, and this system starts right up?

History: i had had problems with using the upgrade, i would lose everything but the background on startup, so i formatted the hard drive and then loaded the full version of windows 7, from the upgrade disk. The problem mentioned began then.

If the file is actually missing , why will it work with the hard drive, and yet not with the disk drive?

Office 2007 File Association Icons Missing

File association icons missing, namely office 2007 icons and adobe programs. Nearly a month ago my file association icons just disappeared for a select few programs and file types. Currently the programs missing the icon/displaying a blank icon are: itunes, adobe reader 9, adobe audition 3, and all the programs in the microsoft office 2007 suite (word, excel, publisher, etc. ) As well as .doc, .docx, . Xls, . Xlsx, and all other standard microsoft office file type extensions and the adobe acrobat default file extensions. (.pdf)

I have tried all the standards: uninstalling office 2007, re-installing office, restarting before/after installs/re-installs, anything regarding the icon cache, resetting default file types etc. All that is shown is a blank "file" icon however, the program still launches upon selecting the files it's just quite annoying needing to view the file types to determine at a glance what program will open selected file.

Error Message - Missing Or Damaged Dll File - Msvcr71.dll

When i boot my computer, the following error message displays each and every time: "the program can't start because msvcr71.dll is missing from your computer. Try reinstalling the program to fix this problem. Exactly what is this error message, how did i begin receiving it and what can i do to fix it.

I've seen numerous so called "fixes" but i am very leary of just downloading anything that says, "i can fix your problem" because you never know who you can trust when it comes to the internet. This is the reason i came here w/my issue. Can anyone help me with this? If so, i really appreciate you and your time obviously, this is a missing dll file problem but i am not certain as to what is the best thing to do to right the wrong.

When installing win 7 64 bit from dvd on a blank hard drive (i hit format before installing) it goes through installation and at the end i get a blue screen with errors 0x0000003b nvlddmkm.sys. I have a nvidia 280 gtx vid card, evga nforce 780i sli motherboard, 6 gigs of ram, quad core intel 3gz processor.

Suspected Virus In Disk.sys

My security software is reporting a virus corrupting disk.sys. Their solution: remove the file. I restored an older copy of the file (though it appears to be the same size, etc. ) To another location from a backup i had, and when i check it, it doesn't report any virus. But the existing copy, c:windowssystem32driversdisk.sys, does. So:1) is this file required for proper operation of windows 7?2) if so, how can i repair the apparent problem?Thanks. (Btw, i took ownership of the file but i can't open it to run a compare on it; it says i need permission from he owner, even though i *am* now the owner. Nor can i copy the file to another location. I don't get that. )

Classpnp.sys Blue Screen

I upgraded to windows 7 professional from xp about 3 months ago. The system worked really well until earlier this week.computer was switched off correctly but on switching on a few hours later the system went into a continuous loop of restarting itself. If i try to load in safe mode the system stops at classpnp.sys. I have tried to re-install from the windows upgrade disk but it seems to go so far and then just stops or i get the blue screen.

I have checked all the message boards but so far there is nothing that has worked. This is the only pc that i have access to that is running windows 7 - all of the rest are on xp. I dont care if i lose the information on my hard drive as it was all backed up before i upgraded to windows 7.

Bsod Stop - Tcpip.sys 0x000000d1

Bsod stop in tcpip.sys 0x000000d1 driver_irql_not_less_or_equal with intel proset/wireless drivers. I have a dell inspiron 1520. I upgraded from vista home to windows 7 ultimate. Since that i had already 3 or 4 bsod on tcpip.sys. Before the upgrade win7 detected 3 incompatibilities:

Skype 3. 8
Intel proset/wireless
Network monitor 3

I would have solved the problems but when i click ok the installation continued. After 7 hours to finish the upgrade (including downloading 1gb+), i was done ie8 was l sometimes crashing randomly. I partially solved the problem moving to firefox but when i forget i still have the problem now and then. Anyway, i need to fix the blue screen of death problems.

After the win7 upgrade, i upgrade the video drivers nvidea 8400gs, skype, network monitor 3 and the intel proset/wireless drivers. I think the problem is in the intel drivers becasue the bsod is on tcpip.sys. I downloaded the drivers here: http://www.Intel.com/support/wireless/wlan/sb/cs-010623.htm through the automatic detection.

It now find:
Product detected  intel® wireless wifi link 4965agn 
Current intel® proset/wireless wifi connection utility installed  13. 1. 1. 0 

These are two logs that win7 showed me after reboot after 2 different bsod incidents:

Netw5v64.sys Driver Issue Causes Bsod

I began getting the bsod randomly and frequently. In the time between yesterday until now, i have gotten nearly 30 bsod's. I know enough about computers to pinpoint the problem, and after debugging to the best of my ability, i determined that the driver netw5v64.sys was causing the crash.

Here is my pc info:
Dell inspiron 1525
4 gb memory
2. 4ghz duel core proc.
Integrated intel video card ~ 965chipset (i think this is correct)
280gb harddrive

The crash occurs at random, but only when i am accessing my wireless network adapter
Conditions that have changed that might have caused this:

- Yesterday around 2:00 i connected my computer to a netgear router. I live on a college campus that uses cisco security, but i wanted to broadcast my own wireless direct from an ethernet connection. I disabled dhcp and all router security. It worked and i was then able to connect through the wireless network i created into the school internet.

Other than this i cannot imagine what the problem is, and i cant seem to fix it. I have reinstalled, uninstalled, and updated all the wireless network drivers. I have check internet forms and i have found that a number of people running 64x windows are having this same issue!

Nvraid.sys Bsod When Drive Added

I have a home built computer that was working wonderfully with windows xp, however windows 7 professional 64 bit has been giving me some headaches.

I did a clean install a few days ago. I can get windows 7 to install perfectly on a single pair of mirrored sata hard drives. I set up my machine with the system and all of my programs on this drive c: everything works great. I keep all of my files on a second set of drives f:.

When i shut down the machine and add in another mirrored raid of two sata hard drives f:, the machine boots up and i can see the f drive and read and write from it for about 2-3 minutes and then consistently bsod's.

The blue screen points to a driver failure. Nvraid.sys driver_irql_not_less_or_equal. I have a .dmp file with the crash but i'm not sure how to share it here.

I'm at a bit of a loss as to what to do at this point. I've tried microsoft tech support and they just threw the problem to nvidia, which i doubt will support this 4+ year old motherboard, but who knows. I may have to go back to xp until this gets ironed out or i upgrade my motherboard.

Bsod - Usbhub.sys On Shutdown / Hibernate

A few days ago my computer with a recently installed windows 7 build 7100 start getting a bsod every single time i shut it down, restarted it or set it to hibernate. I've tried updating all ubs drivers in device manager but they were all up to date and didn't help. I tried restarting it with not a single usb device plugged in. I normally only have a usb mouse and sometimes a exhd or ipod plugged in, standard stuff. I tried doing my own research for the problem elsewhere but couldn't find any answer.

I also tried windows update and installed these three new optional updates but that failed to make any difference either. What other information do you need about my computer to diagnose the problem?

Nvlddmkm.sys Driver Causes Blue Screen

The nvlddkm.sys driver for my geforce 6150se nforce 430 graphics card causes a blue screen of death whenever i watch a youtube video for a long period of time. I re-installed windows 7 ultimate 64 bit, and it still does this. I run windows 7 ultimate 64bit, skype, teamviewer, pidgin client, mirc, firefox, kaspersky internet security 2010, opendns updater, itunes, and outlook 2007.

This problem has caused an unbootble machine when it first happened. It stops happening when i uninstall the nvlddkm.sys display driver, but when it gets reinstalled via windows u[date, and i reboot, it blue-screens. When i re-installed the os, i could work normally again. I am afraid this problem could start again however.

Athrxusb.sys Driver Problem Driver_irql_not_less_or_equal

I have been having a terrible time with a new computer i have purchased, it is the infamous driver_irql_not_less_or_equal. After searching the internet relentlessly for a solution to this problem, i have decided to post my own question, because it seems that this error is caused by faulty drivers or not properly installed drivers. I then searched for the driver named in the bsod, athrxusb.sys, and found it belongs to my smcwusb-g, part number 99-012084-552.

I have followed the procedures of many forums before deciding to post, i have tried uninstalling old drivers, moving the wireless adapter to different usb ports, and reinstalling the drivers. I also used programs such as device doctor to locate old and outdated drivers to replace them.
I would just go buy another wireless adapter, but i am worried that the driver, athrxusb.sys, will be required for any wireless adapter, no matter which i buy. I have seen that this error spans across multiple versions of windows operating systems, why not release a patch to fix this error? Is there one? If there is can it become more readily available to the public?

Ultimately i would like to fix the solution, buying a new device is not out of the option, i just want my pc to be able to connect to the internet without causing a bsod and wireless is the only option.

Unable To Create A Virtual Memory Pagefile.sys

Since i upgraded from vista ultimate 32-bit to windows 7 ultimate 32-bit i have been unable to create a virtual memory pagefile.sys. Everything was fine before the upgrade but no longer. If i try and specify new vm parameters on the vm dialogue everything appears fine. The new drive and size specification are accepted without incident. I click ok on all the parent dialogue boxes until they are all closed. If i then drill down through the same dialogue chain, when i return to window where i originally entered the details, they are nowhere to be found. My previous location and size specification are gone.

Netbook Cannot Start - Safe Mode Stops At Classpnp.sys

My msi u130 windows 7 starter does not start, merely gets to the loading screen (where you see the green flash going above the words microsoft corporation). Launch startup repair shows a white bar and the message windows is loading files before going to the loading screen. Launching os recovery does the same as above. Using safe mode hangs at 'classpnp.sys'. A variety of other safe mode options stop at 'classpnp.sys'.

I downloaded the windows 7 recovery disk iso and put it on a usb. After some problem with "ntldr is missing press ctrl alt del to restart" downloaded bootsect.exe, used that, then got a message windows is loading files and a white loading which, which, when complete, put me back tot he normal windows loading screen, zero other activity. Have tried to boot to a linux system off a usb to replace the classpnp.sys file with one i found on this xp machine, but can't get linux to start off the usb. So any ideas? With my main laptop with my wife i desperately need this netbook working, not least because it has office 2007 on it.
