Under NT4.0 SP3 the sequence of:
WSAStartup(MAKEWORD(1,1), &data) / socket() / bind()
We moved to NT4.0 SP4 and the above sequence failed. We changed to:
WSAStartup(MAKEWORD(2,1), &data) / socket() / bind()
and this worked fine.
We have moved to NT4.0 SP5 and I cannot find any working combination.
Question: What's the difference between SP3, SP4 and SP5
and what do I have to do to get SP5 to work?
