In my corporate office we have a Cisco 5520 ASA firewall which we use as our DHCP server. We were on 8.0(4) IOS and on Friday we upgraded to the latest IOS 8.2(2) and this morning all the PCs in the corporate office were not getting an IP via DHCP.


We reverted back to 8.0(5) and we stated getting some DHCP requests to go through but again new machines were not getting an IP address. I am now at a complete loss as to what may be causing this issue?

Has anyone ever seen this or heard of it before? These are all Windows XP/7 machines in our office and use HP Procurve switches.

Any advice is appreciated. Thanks!
