Hi,

Just as the group thread which JianWei mention figured out, this is known
issue to the VS2003, the problem is in atlmfc\include\atlsocket.inl. This
class now uses the following functions:

FreeAddrInfo()
GettAddrInfo() and such.

and those are only defined for _WIN32_WINNT>=0x0502. ATL code should work
for all supported platforms, which includes Window 2000 platform.

This issue has already been fixed in the VS2005, but currently we do not
have a specific hotfix for VS2003, so in this scenario I suggest you can
try the workaround which is contained in that newsgroup thread, wish it
could also work in your case.

Thanks for your understanding!

Best regards,

Gary Chang
