This morning I ran zenmap against our domain controller (windows 2003 server) and found an unknown open port
Discovered open port 10180/tcp on 192.xxx.xxx.xxx
Through various google searches I found it is commonly used as a quickbooks database port which shows ways to open the port but no way to close it. i found this site that shows how to open it with windows firewall but when I ran the instructions to close the port it was not visible as an open port.
I'm taking the tried and true, close the port and see who yells approach on this one, any ideas?
