Thanks again for all your help Thirumal,
I tried the solution from the ittoolbox link. It seemed to suggest not using the fully qualified name (which I was already doing). As a second check I tried using just the IP address of the installation server, but still had the same result. Both of these tests were done in against a Windows 7 host machine, and neither resulted in any logs.
I've also opened up message 574504 for this issue.
