Hey guys,

got a client who's getting a lot of these. I've never had to deal with these before. There seems to be two audits which keep failing over and over. I'm more concerned with the first one. Am I right in saying that it looks like someone's trying to hack the system? And if so, is there something I can do?

It's an SBS 2008 box.

Actually, now that I think about it. the second error is from a laptop which is on the network but isn't connected to the domain. he connects his Outlook to exchange.

Thanks

221.204.230.57 is owned by China Telecom and; almost without a doubt, someone is trying to hack into your server.  If you want to start doing something about it get Tweaking.com's Block Ip tool ( http://www.tweaking.com/content/page/remote_desktop_ip_monitor_blocker.html ) and IPNetInfo ( http://www.nirsoft.net/utils/ipnetinfo.html ).  When you get a rash of the failed logins; use the Block IP tool to stop them, IPNetInfo to find the entire range, and learn how to edit the blocked ip's so they cover the entire range.  It will take some time; but, you'll soon have most of the hackers blocked.
