I ran into a issue at a customer site that has me scratching my head. The setup is as follows
ASA 5505
0/0 set for internet access (Outside)
0/1 set for internal (inside)
0/3 set for Wifi Controller
Everything works as designed with no issues. We were decommissioning some old 2003 servers... When I shutdown a particular 2003 server the internet shuts down for the business. Bring the server back up and everything flows normally.
There is no ICS internet sharing through that server.. there are no certificates, no custom routes and no custom rules for that server besides an object in the ASA.
Any direction that you could point me in to see why just this particular server stops the ASA from external communication?

Hello
Can you post the config of the asa please?

Hello,
The server can be for the network:
-a DNS server
-a proxy server
-a dhcp server
-active directory with policy etc.
You must know the ip address of the server and search to see under which config is the object applied on the ASA. (dhcp relay, dns server under dhcp server, proxy server on the hosts config etc)

Another guess: The old server is the DNS-server for the company?
