Problem in executing command "ipconfig /flushdns"

[Mr. Low]

Dear Sir,

I was having some internet connection problem recently.

My ISP recommended me to execute "ipconfig /flushdns" at the command prompt.

I performed the following steps:
1 - Click on "Start" button, go to "run"
2 - Type "command", click "OK"
3 - Type in "ipconfig /flushdns", then press "Enter"

When I completed step 2 the following error message appeared:

16 bit Ms Dos Subsystem
C:\windows\system32\command.com
C:\windows\system32\autoexec.nt. The system file is not suitable for
running MS Dos and MS Windows application. Choose close to terminate the
application.

May I know how to overcome this problem ?

Is this command harmful for my PC ?

Thanks

Low

What happens if you type cmd instead of command and then type ipconfig /flushdns at
the cmd prompt?

"command.com" is a legacy command processor from the old
DOS days. Starting with WinNT in 1995 or so, cmd.exe is
the correct command processor to use.

Hello Brian.

I have succesfully flushed dns resolver cache after following your steps.

Many thanks

Low

Glad to hear it. Has it resolved your issue? FYI, typing the older "command" does
work, yet it may not work for all machines. Now that you have flushed the DNS,
register it.
At the cmd prompt type each line below and the press Enter after each:
ipconfig /registerdns
exit
