Hey guys I am having an issue with lots of Unidentified calls on the server. Is there anything I can do to avoid this?
it doesnt seem to happen in all the systems that I run just this one. They are all setup the same.

Unfortunately if your server is in the IP range the hackers are spamming it will keep happening. You could tighten your firewall rules to only allow connections from known IPs.
Also turn on the Global blacklist if you haven't done so already. Apart from that, just follow the basic security procedures and you should be fine.
