Hi all,

I have an AP 1200 from cisco and use IAS on a win2003 server.
I don't have any issue logging using PEAP and my Windows XP client get a
lease from our DHCP server.

But after a few minutes, it seems to reauthenticate and then I'm unable to
have a lease again. I get then a 169.254... automatic address.

If a change the radius server with a ACS from cisco this is the same and the
log tells "NAS duplicated authentication attempt".

any idea would be welcome...
