when i wrote my first mail with this content, I received only the lists digest. To be able to answer, I switched this, to single message mode.
So, here again.
I have strange performance issue with an single Windows 7 client in a
simple network setup with one samba server, and various windows clients
(Win XP, Windows 7).
All clients can open shares with explorer, without any delay (the share
contents are listed directly).
But one client, a lenovo Windows 7 Laptop has strange problems opening
these same shares. The time from opening a share, until the share is
listed, varies betwenn (seldom) direct response, and in most cases
delays between 3 and 20 seconds, in seldom extrem cases 1-2 minutes.
It is does not depend on the switch port. The problem also appears
while being connected with other switch ports, different ethernet
cables or on a WLAN/WIFI connection.
Because this is the only Windows 7 client with this kind of problems, i
reinstalled the machine from scratch (with the lenovo version of windows
7 from the hidden partition), hoping this problem was caused by any kind
of windows weiredness (the windows 7 installation was one or two years old).
The only change was, there were no more delays in listing shares, longer
than 20 seconds, so the core problem still exists.
What possibilities do I have, to solve this problem?
My next step was, to capture the network traffic this client does, while
opening an specific share. I captured also the traffic caused by two
other windows 7 clients, which do not have any delay issues while
opening the same share. My knowledge about samba network packages is far
to low, to be able to find the problem.
In my desparation now, I joined this list, hoping there is anybody, who
can give me a hint to the right direction, to solve this problem.
Is here anybody who can "read" this traffic dumps, and may be see whet this clients problem is?
I could also post thes three traffic dumps, they are small (about 15k each).
Who can i contact, to help me solving this problem?
