I have a LAPTOP that will not access any other computers on the network. It will go on the internet and acknowledge the presence of other computers on the network (on the network tree) but will not show any shared files or other computers for that matter. Today I deleted some old network settings and now the laptop is recognising my network as an old network no longer in use. I'm ASSUMING that the settings have just become fragmented and jumbled so, is there any way to reset all my wireless settings and history?

Windows Vista btwahh this is INFURIATING! I have deleted as much history as I can (no registry changes), deleted and reinstalled the wireless drivers and still it will not connect to the other computer. It's not a FIREWALL issue (disabled it on both sides, moderate improvement once zone alarm is off).

I'm out of ideas... wait I now have media sharing...What changes were made since it worked last?
Have you tried using System Restore to take it back to a point where it worked?It never worked. I suppose a system restore to win XP would work but then I loose DIRECTX 10, the only advantage of Vista.
