Im not sure if you can get this to the event log, but the ip address should be logged to the text file iis log (as long as logging is enabled). You can parse this log file and then add the rules. You could parse this file, and use wmi to add an ip blocking rule to iis.. rather than having to hit the firewall each time..but just an idea.

Subject: OT: Win2k3 logging the IP address of failed FTP attempts

Hi,

Sorry for the slightly off topic question but I find myself at a loss and would like to query
your collective intelligence.

We have a win2k3 web server which hosts a few hundred domains. Recently I have
noticed a load of brute force attempts against the administrator account coming from
China. Not unusual but today I noticed ;)

Unfortunately the IP address is not logged to the event log so I have had to use
TCPView from SysInternals to figure out where they are coming from so I can block
them at the firewall. (Easier than looking through the FTP logs of a hundred+ sites.)

Does anyone know of a way to get the IP address into the event log? I have all the
auditing rules switched on (ie. success,failure) but with no results.

I wish to get the IP address so I could then automate the blocking of IPs for a set period
of time.

Sorry to post this here but a full work day of googling has left me with nothing.

Regards

Ian
