That's not what I meant. Do this instead:
1. Click Start / Run / c:\winnt\system32\cmd.exe {OK}
2. Type these commands
c:\winnt\system32\ipconfig.exe {Enter}
c:\winnt\system32\ping.exe 192.168.1.1 {Enter}
3. Report the results.

I can ping the router. I am trying not to get ahead of myself. What next?
 
Your very initial problem was that you had a "16-bit MS-DOS
Subsystem" error. You are not getting it now. This means two
things:
- The file c:\winnt\system32\ping.exe is intact.
- You have a malware file somewhere. It could be
c:\windows\ping.com. Get rid of it.
Since your most recent post does not mention any further
problem or error message, I assume that your problem is
now resolved.

For better clarity of your posts, try to be highly specifc.
Instead of writing "the same problem" and "with the Command
Prompt", you might say: "I can open a Command Prompt
but when I run ipconfig.exe then I get a 16-bit MS-DOS
error". This would avoid a lot of guesswork and running
around in circles.

The answer is simple:
- Start a Command Prompt, using c:\winnt\system32\cmd.exe.
- Type the full name, i.e. c:\winnt\system32\ipconfig.exe
- If the problem persists, replace ipconfig.exe from your Win2000 CD.
- Report the result.

I think a sfc /scannow would help the OP.

Get your Windows CD ready, drop it in your cdrom tray, and run sfc
/scannow (now, does the virus/malware replace or circumvent sfc? we'll
find out).

Good luck,
