In windows server 2003 when an Event 529 (logon failure) occures with a logon type of 10 (remote logon), the source network IP address is recorded in the event log.
On a windows XP machine, this (and some other details) are omitted.
If a bot is trying a brute force over RDP (some of my XP machines are (and need to be) exposed with a public IP address), i cannot see the originating IP address so i don't know what to block (with a script i run every few minutes).
The DC does not log this detail either when the logon attempt is to the client xp machine and the DC is only asked to authenticate the credentials.
Any help getting this detail in the log would be appreciated.
