Copy the AUTOEXEC.NT file from \WINDOWS\REPAIR to \WINDOWS\SYSTEM32
If it asks you whether you want to overwrite,
click yes

Yes, im getting something similar to what i see above. My case is only slightly different.

I have recently installed an ADSL internet connection on my laptop. It worked perfectly fine for the first several days.

However, now, when i connect the ADSL line everything is fine for a minute or two and then suddenly the connection crashes. This happens for both internet explorer and firefox.

After the crash occurs, if you go the icon to reconnect to the internet using ADSL, nothing happens. You click on this icon and nothing occurs...zero. Its like it may as well not even be there.
Also, a couple minutes after the crash, i receive the following pop up message;

Subsystem MS-DOS 16 bits (this appears in the window pop up header)
Quote:
C:\WINDOWS\system32\command.com
C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The file of this system is not appropriate to execute MSDOS applications and Windows.
Choose 'close' to finalize the application.

Then you choose 'close' or ignore with the exact same result. The window closes and your are still unable to reconnect to the internet.

So, my first idea was to reinstall the ADSL internet software. This works...however, the problem just reoccurs and im back to square one.

So the problem appears to be in this 'command.com' MSDOS file in my system32 folder. For some reason it has all of a sudden started to not get along with my ADSL connection.
What is strange is that it was working fine for several days then it started.

I have cleaned my laptop for viruses and found several but they have all been eliminated. Same with spyware. All viruses i found seemed to have no connection to this 'command.com' file but maybe one caused damage to it somehow.
Im just not sure.

Some people have suggested reinstalling windows but id prefer to wait to do this.

If anyone has any suggestions or experience with this, id love to hear about it.

Thanks in advance to anyone who responds.

Cause:

This issue may occur if one or more of the following files are missing or damaged:
Config.nt
Autoexec.nt
Command.com

Resolution:

To resolve this issue, perform any one of the following three procedures:

Procedure 1: (Successful and easy to perform)

Please install a patch from the link given below. When the patch downloads save it on the desktop. Then right click on the downloaded file and choose Extract to and make sure that you choose the directory C:\Windows\System32. If you have got the right directory you will be asked if you wish to overwrite the existing files. Say yes, reboot and try your program again.

Well,

I personally don't believe this is an issue with spyware or the like.. I believe that you just have old versions of
Config.nt
Autoexec.net
Command.com

Follow this MS KB Article to resolve the issue http://support.microsoft.com/default.aspx?scid=kb;en-us;324767

Thanks,

Boot in Safe Mode and see if that helps. If not it's time to reinstall Windows.
