Well, I can see the delays in the capture, but the snarflen for the capture is a little too small to tell much else. Can you redo the capture with a larger snarflen (maybe -s 512 or so)? Also, were you able to tell anything from a server-side capture? Is the server issuing oplock breaks at those times? Cheers, Jeff
