Re: Follow Up: Wireless Authnetication to AD Network

I have this exact scenario working across a large multinational corp. PEAP/
MSCHAPv2 is the way to go.

Things to look out for:

1. Only windows 2000 sp4 and XP SP1 and above can truly use this without
external apps
2. XP sp2 is the most reliable way to get this going
3. Many of the WLAN helper apps can interfere. Standardize their experience
by unstalling these and letting XP handle the connection -- or standardize
on one kind of card and use that driver only.
4. Have backups of your IAS implementation and use the MS IASImport utility
to duplicate server and WAP configs
5. Plan well for any PKI you are using to manage the certs that you'll need
for IAS servers.
6. Cisco WAPs are the most reliable for this and I wouldn't consider other
equipment for this.
