I keep getting this error when I run start.bat on WinXP: The disk w is busy. Use start.bat [disk letter] . Press any key to continue . . . I uninstalled Skype, Google Earth and anything else that I could think of that might be conflicting. I tried to ping localhost and when I do it from the command prompt it tells me: C:\UniServer>ping localhost 'ping' is not recognized as an internal or external command, operable program or batch file. but when I run it from the Run line, it says: Reply from ::1: time<1ms Reply from ::1: time<1ms Reply from ::1: time<1ms and then disappears so quick I can't see the message. I know that there is a setting to keep it open, but help returns the same message as ping. Any assistance with this would be appreciated. I am developer, but I'm not very knowledgeable as far as system stuff. I am trying to get Ruby on Rails to run, so if you have any pointers on that, I would really appreciate it. Thanks.
