I had a link to a white paper from Microsoft which describes the NT5.0
TCP implementation. Apparently page is no longer there. But answer to
your question from that document is

" By default, Windows NT 5.0 resends a segment if it receives three ACKs
the same sequence number, and that sequence number lags the current one.

This is controllable with the TcpMaxDupAcks registry parameter"

It has fast retransmit.
