802.1x, XP client not renewing IP address after VLAN changes

-

 

 hello,

we having issue testing xp sp3 windows clients on our new wireless 802.1x solution.

our symptom:
when xp client @ windows login screen. expect machine authenticate network , placed in role.  after user passes user credentials, radius places user in different role in different vlan. our issue ip address dhcp doesn't renew after first authentication. work around release , renew ip address now.  


environment:
aruba 6000 wireless controller
ap 70 thin aps
windows xp sp3 clients
dhcp served 2 windows dhcp servers split scopes.
 
i not sure if our issue related http://support.microsoft.com/kb/928233  because not running vista or sp2.

corrective actions tried:
1. patched windows sp3
2. updated intel pro drivers.
3. searched dhcpconnforcebroadcastflag in register. not think applicable windows xp. vista.

hi,
