Hi, I hope someone has an answer!
I have a couple of mac users who when trying to transfer large amounts of data (be it as one big file or lots of single files at once), it starts nice and fast and after around 2GB or a bit over it slows to a crawl. It is an SMB share the mac users are connecting to. Also it actually will just die eventually when you think its nearly done. ie a 4gb file and it falls over at 99% with a second to go...DOH! After waiting god knows how long for it to copy across to that point in the first place.
Transferring smaller chunks is fine, however theres far too much data that needs to be archived to an external disk array connected to the SBS Server for us to be doing 2GB chunks.
Ive tried everything I can think of, including removing ISA and also disabling any offloading done by the network card in case that was being overwhelmed somehow.
Also I can't try apple shares due to it being a legacy protocol only supporting something like 30 characters, tried that but that was far too limiting!
I'm going to try an ftp site out to see if its to do with smb?? Or whether its more generic than that.
It just weird. You can see the network card being utilised nicely then just over 2gb bham it drops to using next to nothing......other users arent affected their connections to the server carry on working fine as they were while transferring the data. Is there some sort of limit somewhere? Also netstat -an shows me ports aren't being used up or something similar which crossed my mind.
Can anyone provide any clues??? I'm lost.
Thanks in advance
