I have got an aerohive network which runs over an MPLS network. At a site, we have got 3 SSIDS published, staff, guest and corporate. The staff and guest use WPA, and the corp uses Microsoft CA server and NPS server for the RADIUS. User can connect ok to the staff and guest, get and IP address and do what they need. The Issue i have is with the CORP, the end uses gets a self assigneed IP, 169.254. From looking at the client monitor, and debuggin on the cisco switch i can see the DORA process, the client send out a discovery message, the DHCP offers a message, but the client never acknolges it,and then times out. The setup is woking in HQ and the client i have been using works, there so i know the laptop is fine. I have also tried assigneding a static address and this to want connect, but the 2 ssids using wpa work fine, so there is somthing up with the RADIUS but i dintr know what and was hoping someone on here might be able to help?
