My understanding is that Win2K will still come shipped by default to only use a tcpwindow size of 64k. Although NT4 couldn't comply with RFC1323 which allowed for larger sliding windows, W2K can. To do this however you will need to "edit the registry". You then could change the setting in TSM expecting it to work.
I have not actually done this but there are many references to changing the TCP windowsize in W2k for larger packet size networks. My suggestion is to go to google and search for "windows 2000 tcpwindowsize rfc1323". There are microsoft knowledgebase articles discussing this as well as other heplful articles put together by users. You will need to ensure that the AIX TSM server also has RFC1323 enabled and a larger TCP windowsize for this to most benefit you. Changing the settings in TSM and not the OS is fulile :-) Thanks, Cameron.
