slow smb traffic

[davez]

currently have some issues coming from an apple xserv to a win xp box in that the file transfer is very slow. going the other way is fine. i have done a packet trace (attached) and have noticed that packets 1 - 8 show no probs but it gets unusual from packet 9. the xserve is xx.xx.xx.70 and the windows client is xx.xx.xx.51. The sequence numbers in packet 9 jump from 7300 to 16060 which seems to be the cause of the problems does any one have any ideas what this means?
