I am using the same settings for TCPBUFFSIZE and TCPWindowSize and it works
for me too.

Although, this is what I see in a sniffer capture (Ethereal) during a backup
(Win2k server):

TSM Server --> TSM Client               TCP window size is 17162
TSM Client --> TSM Server               TCP window size is 65535
