Ntoskrnl.exe

[Adam]

I keep on getting the following message from my firewall on a near daily
basis.
"Ntoskrnl.exe" has changed since the last time you opened it. This could
be because you have updated it recently. Do you want to allow it access to
the network?

I then did a search on my pc and found that I had one in my
windows\system32 folder and one in I386\driver.cab folder. I deleted the
latter one.

Today I got the same message ""Ntoskrnl.exe" has changed since the last time
you opened it. This could be because you have updated it recently. Do you
want to allow it access to the network?

I did another search for ntoskrnl and now I have a number of ntoskrnls on my
pc in the following folders:

Recycle bin
C:\I386
C:\I386\driver.cab
C:\I386\SP1.cab
C:\WINDOWS\system32
C:\WINDOWS\drivercache\I386\driver.cab
C:\WINDOWS\drivercache\I386\sp1.cab

I am up to date on virus definitions and I have done a virus check.

I have added some MS critical updates etc and I have been trying out
different browsers but besides that no major changes on my PC.

Any idea what is going on? And what do I need to do.

Hi, Adam.

I then did a search on my pc and found that I had one in my
windows\system32 folder and one in I386\driver.cab folder. I deleted the
latter one.

You deleted the wrong one. The one in the windows\system32 folder is
actually installed and working. The I386 folder is basically a copy of what
came originally on the CD-ROM and may have been moved to the HD just in case
you need to refer to it later. In addition to the ones you listed, there
should also be a copy in windows\system32\dllcache; this one should be the
latest one from updates you've installed.

Run the System File Checker. At the Run prompt, type: sfc /scannow

SFC will compare each WinXP operating system file with the "known good" copy
held in your cache and replace any missing or damaged ones. It updates the
cache whenever it installs a Service Pack or hotfix. If your cache does not
contain the proper file, you may need to re-apply the upgrade that contained
it.

My WinXP Pro is current with all Windows Updates (as of yesterday). My
ntoskrnl.exe files in windows\system32, window\driver cache\I386, and in
windows\system32\dllcache are all 1,925,760 bytes, dated 4/24/03.

Hi RC

While running system file checker I get a message saying

Files that are required for windows to run properly must be copied to the
dll cache. Insert your Win XP Home edition cd rom.

I only have a recovery disk and when I insert it I am told that this is the
wrong disk. How do I get round this.

Point to the I386 folder.
