I have Windows XP Home and for some reason, all of a sudden I am unable to run any kind of commands in the Command prompt under Start - Programs - Accessories. I used to be able to run things like system file checker and ipconfig but for some reason I cannot now. Could DOS be corrupted or am I just accessing things wrongly. Last time I tried to run IPCONFIG I received a message that said "IPCONFIG is not recognized as an internal or external command operable program"....Also when I open up the command prompt it says C:\Documents and Settings\Username. That's right isn't it?
