Hopefully someone can give me some guidance here. MS-DOS was working fine as I had just did ipconfig to get my IP address. Then I downloaded a new Java SDK 1.4.2_09 and part of the installation procedures called for me to change the path in the Environment Variables. Now, dos won't do anything as far as ipconfig or nslookup or anything. Can someone tell me what the default path is for the environment variables or can i have one that permits both javac and ipconfig in dos?
