Thats my Server that they try to log into (I changed the name here)

Okay, this has to do with IIS on the same box ? Do you need to have IIS on that box ? Can you describe more on 'role' of this box ?

yeah i have IIS on it, and that needs to be on, i do have IIS logging enabled, but they are just a pain to look over, and so far I could not see anything weird. I need IIS for Exchange web access.

I don't know but you should also have some more logs pertaining to the same. You need to find out the Event ID and only then this can be correlated to what problem it is coming from.

Yeah but I dont get this often, only around 1:00 in the morning, and only on the weekends. (not every weekend) And they keep trying different usernames, such as admin, guest, webmaster, and so on. We had somebody laid off a year ago, who right after that tried to log on, and always around midnight-early in the morning. He cant sleep. He might be back. I need to find out the IP address where they are trying to log on from.

rsivanandan

hmm, I understand. What kind of network infrastructure do you have ? You can enable logging on firewall or router and monitor it to see the inbound connections.
