I'm trying to connect wirelessly to the other computers but I can't seem to do that for some reason. My computer has had to start all over again and there may be corrupted files, but in order for me to fix the computer I need connection with the internet. I phoned BT for help - didn't really help [as you can tell]I gather from another thread of yours that this is Vista and that service doesn't exist in Vista.
(SP2 I hope).
Wireless Zero Configuration was first introduced with Windows XP.
In Windows Vista it was renamed to "WLAN AutoConfig". If that's present then try it instead.
An outline of whatever the problem is would help.
