I felt like making a ping to my router, when for no apparant reason it didnt recognise the command.
So then I tried a bunch of other basic commands (HELP, ?, go, ipconfig, etc. )
So far only CD and start commands worked...

Help please! Ive no idea whats going on  Are you doing this in strictly DOS 6.22 or older -or- Windows DOS Shell DOS 7.0+?

If Windows is running, then its Shell and should RECOGNIZE those commands, but if 6.22 or earlier many commands didnt exist yet for TCP/IP Networking on original 6.22 installation without ADDITIONAL 3rd party software that i know of.

Im running windows vista 64, dunno what version it is, i just open the command prompt :SWhat message do you get when trying to use these commands? Is it the same message if you try and run hello at the command prompt?check your PATH variable. maybe system32 (is it?? ) is not thereI checked the path variable and when I changed it to C:\windows\system32 the commands started working again, thank allot ^^
