Win 2003 SP1 & TCP_WAIT issue
I discovered that with Win 2003 SP1 for some reason the FTP Socket is getting stuck in a TIME_WAIT state.
Because of the new design microsoft did with the tcp/ip stack with sp1, if the state does not go to ESTABLISHED then windows will kick out the connection after 60 seconds.
As a temporary messure to get around the issue sending a NOOP command every so often will keep the connection up as it uses a new client port number, however it causes a problem with users not wanting to allow the noop command because of idling.
