Is there any way to get XP Pro to log the source network address in event 529 - or in another event? I am logging event 529 but there is no source IP address shown.

It is probably because of the authentication protocol in use.  Can you post a sample of the event - obfuscate anything sensitive.

I guess there's a difference here between what gets logged for this event between XP and 2003.  2003 logs this.   I thought XP logged this same information but from your post - apparently not.

Having a similar problem. Our SIEM monitor receives the below and I can't track it down because no source address. Our SIEM service says several of their customers have the same problem and they've never been able to give them a solution.

Find the raw event on the workstation, what does Network Information show for source workstation and source IP. There should be something there for some of the events.
Workstation Name: WIN-R9H529RIO4Y
Source Network Address: 10.42.42.201
