Unfortunately, the Windows Service pack 2 has a bug (!) You should feel angered at MicroSoft for this (I know I was.) \n\nFor a simpler way to have the network up and running than using the cmd (Which didn't work for me), go to the website listed below and download the patch to address and fix the problem.\n\n\nIf the patch didn't work (and for me, it didn't) then you have no other option but to uninstall "Windows Service Pack 2" from the Add/Remove programs menu in control panel. Now the network works!\n\n(I am not responsible for any inconvienence caused though!)
