What is WSAGetLastError returning when you see the recvfrom error?
And as far as the first patch goes, I believe Jon's intent was to check for
an empty string, not just a null pointer. So I would try:
if ((cmdline->scopes != 0) && (*cmdline->scopes != 0))
SLPSetProperty("net.slp.useScopes", cmdline->scopes);
