I am trying to run ipconfig command in XP operating system but only getting an error message “The request is not supported. Please contact Microsoft support services for further help. Additional information: Unable to query routing information.” I have done the same thing many times before. I was looking for registry error but no registry error was found. I have searched on different windows forum and also asked my friends to sort out this problem but so far all of them disappoint me. One of my friends told me to check up the firewall setting but I found it perfect. Does anybody have any idea what was happened? What to do to resolve the issue?
