We have ~150 remote offices and are looking for methods to inexpensively deploy more computers. One consideration is wireless. The remote desktops already receive their DHCP addresses via a Cisco forwarder address in GRE tunnel of a 1700 series router. Some sites already have 11/12/1300-series aironet on-site where the aironet 172.16.x.x route goes through the GRE tunnel back to the 4402 controller, where the aironets pickup their DHCP address scope. What I'd like to know is, in the interest of managing all of the DHCP from a single GUI, can the 4402 some how lookup/use the DHCP scope on the Windows server which the desktops are using to obtain their DHCP?
