Hi Guys,

Up until now, when a client dropped into an unauthorised VLAN, it used to drop onto our student network and PXE boot worked fine. HOWEVER, Now we have a new scope for the unauthorised VLAN and PXE boot is not working on certain machines picking up an address on that range.

If you remove dot1x from the port on the switch and manually untag the student VLAN, PXE boot works again.

I believe something needs to be changed on the DHCP scope / server to allow the new range to work with PXE Boot....please can someone let me know how and where in Server 2008.

Many thanks
