If the hostname resolution uses a local hosttable, it's possible you resolved to an old obsolete address.

Handle the request as a non-fatal error (if possible), since some WinSock's can legally fail the request. WinSock description: Same as Berkeley. If this tends to occur after running certain applications for a while, it might be a symptom of an application that doesn't return system resources (like memory) properly.
