I havent been able to find time to test this yet - so my question goes out to anyone been able to test this yet? The reason is quite clear - in XP and Vista, while logging on - if you used 802.1x and VLAN swithing (NAP remediation zones etc) you may experience the loss of logon scripts and other important processes, due to the time it takes to switch VLAN and recieve a new IP address. Do we know if this has been changed in Windows 7?Does the logon processes know about the network changes and restarting the scripts or other redundancy methods? Another key question is - is the network layer "smart enough" to wait for the VLAn swith to happen, resubmit a DHCP REQ in a timely manner (compared to XP's behaviourunder VLAN swithing) Appreciating any inputs on the issues :) Sincerly, Jon E.
