Have you taken a packet trace of it? E.g. perhaps the failure occurs
during the lookup? Capture both cases and then look for differences
in the two flows.

Because you are already using a proxy it may not be possible to use a
proxy tracer (such as FiddlerTool) but you should be able to use netcap
and then format the resulting .cap file with Ethereal (for example.)


Good luck
