We had a pair of ASA5550 that we swapped out with a pair of ASA5580. While the 5550s were running the only Windows 2008 server on the network was running fine. The rest of the servers are 2003. After the swap the 2008 server has issued with the IP address, it has an entry in its own log saying that there is a duplicate IP address in the DMZ, but the offending MAC address is the ASA's DMZ interface address. The server guys deployed a 2003 server with the same IP address to test and it was working fine. Did any of you see this before?
Please make sure that you dont have any static (DMZ,DMZ) or something like that, if you still face the same issue and that static is not configured, please try to disable proxyarp on that interface,
