I am trying to have my wireless users authenticate the machines on one vlan and then based upon the user id from AD switch to another vlan if required. I have it working just fine except when the user logs on and ACS forces the new vlan, the IP stack goes to "Limited Access" because the ip address hasn't released and renewed. Because of this until they turn off and turn the wireless card back on they go no where and log on routines such as scripts and user group policies don't execute. Any help would be appreciated.
