Ok, looks like the 64 bit client is using a different level of interest than the 32 bit on the FIND_FIRST call. I suspect that that difference may account for the difference in response time. It's not completely clear to me why that would be. Maybe a windows bug that causes a slowdown with that LOI? In any case, I think we need to look closely at what's happening at mount time. First, I'll need some other info: 1) output of "/sbin/mount.cifs -V" from both machines 2) mount options that you're using on both boxes 3) wire captures from mount attempts on both machines. Try to mount the "clameter" dir on both boxes and do captures of each attempt. Maybe this time use -s 0 with tcpdump so we get all of the traffic. There may be crackable password hashes in the captures, so you may want to send them to me privately and not cc the list.
