Have you tried connecting via a numeric IP address ?
Windows has been known to have some nasty resolver caching
behaviors which, if not registry hacked properly, can
cause it to hang onto a bad DNS resolution for
a long time...so if your target has changed its IP
address recently, the Windows resolver cache may not have
flushed yet.
