So I really don't get it what happened. My network diagnostic command line tools 'are not recognized as a batch file or external command' in command line ( ping, netstat, trcrt...). Files are in Windows XP default folder and in Enviroment Variables path also. But I can do with normal GUI everything. I didn't use command line network diagnostic on this computer for week or more, the only unusual thing is that I installed a couple of new IDE-s to my machine ( Netbeans Ide,Eclipse Juno, ActivePython, IntelliJ Idea and Lazarus). I also have Virtualbox installed more than one month or so.
Is there any chance that Virtualbox network adapters have some conflict with my command line tools ? Or there is something else ?
OS is Windows XP SP3
