so I setup a minecraft server on my laptop and it was running fine for a couple weeks then last night I reinstalled minecraft on my desktop and when I went to login to the server I had to reenter it.ok so I went to cmd and type in ipconfig to get the ip I have to use to connect to the server within the local network well it keeps telling me that ipconfig is not an recognizes as a internal or external command operable command or batch file. I went to c:\window\system 32 and found the .exe and when I run it it shows up like normal in the cmd but closes after a split second can anyone help
