Windows DHCP server refusing IP lease to a RSA client on Wireless LAN

Hi All,

I am running a Windows 2000 server (DC) including my DHCP/RADIUS/CA
and RSA server. I am also using cisco wireless gadgets (access point,
wireless LAN cards) for my LAN. Now my laptop dosenot recieves an IP
address from the server when I am using RSA authentication. If I use a
PEAP authentication it gets the IP address problem free. Even if I
manually assign an IP address to the laptop it is unable to ping the
server (both in same broadcast domain), I have also noticed that my
client gives a continous broadcast for an IP address. I would
appreciate if you network Gurus can help me out of this situation.

Thanks

Cheers, Nitin
