I have XP Pro machines with the RDC 6.0 I have Vista business machines properly set up to allow RD connections from previous RDC versions.
One of my Vista machines works great, the other denies all connections from the XP Pro machines.
Is there a log I can look at to figure out why?

Make sure the Vista Remote Desktop host PC is configured to "Allow connections from computers running any version of Remote Desktop"...

It is already set for that. I should also note that it works when connecting from Windows Server 2003 SP2

What error message do you get on the XP box?

Try connecting again. If the problem continues, contact the owner of the remote computer or your network administrator."

I presume you can ping the Vista PC from the XP PC?
Are you running any software firewall on the Vista PC that may be blocking incoming Remote Desktop requests from specific IP addresses, ie. the IP of the XP boxes?
Are you calling the correct IP? Is this on a local network or over the public internet?
I presume the XP clients are configured like this...

-Windows Firewall disabled by GPO. Symantec AV CE with no Internet Security

-Fails on IP and name, DNS correctly resolving. Occurs both remotely and locally

This has worked in the past. Then it quit, and the other Vista PC I have works. Last night I performed an Ethereal capture to see if the machine was seeing the traffic and the request came in from the requesting machine, sourced from port 3472, destined for port 3389, so I know that part is working. Either the machine is actively refusing the connecting, or the service is not seeing the request.
I am trying to figure out if there is a patch installed that broke it. Do you know of any patches the have been put out on Windows Update or WSUS that may have broken it?
Also, is there a log file I can look at that will tell me why the connection is being refused?

Well you could look at the event logs on both machines. They may or may not provide a clue...

Looked at the event viewer. Interestingly enough, there are alot of messages corresponding to the printers on the remote machine. I configure my RD client to not allow access to the locally installed printers to see if that would fix it. It didn't work.
