Access application slow over SBS network

[mctwist]

Hi all, I have a client which is currently implementing a job tracking
software, and it runs on some kind of Access application. The MDB's
are located on a network share, and the application (.exe), access
them through a network mapping.

I already have looked at pretty much all the info I could get my hands
on, tried a bunch of different stuff and spent most of the day working
on this, plus a couple hours before that. I have adjusted the
antivirus so that it does not scan mdb, ldb, network files, and the
application. It works fast from the server, but not the workstations.
I ran a test in which I put the DB on a workstation with network
share, and that did work fast, but it's not practical and defenitly
not an option. I finally stumbled across a wonderfull post, tried it,
and it worked.... until I came back from lunch.

The solution is described in this post:
http://groups.google.com/group/micr..._frm/thread/7188759b0c85bf5a/e9f11abbad2c36b8,
also referenced in those 2 MS KB811497 and KB887429. Basically it's
only to disable SMB signing, which seems to be a common fix for SBS
speed problems. At first, I only adjusted the registry. Then, after
lunch went back and tried with the group policy (disabled 4 SMB
policy), updated the group policy, and after a while it worked again.

I had other stuff to do at the client's site, so I went on to work on
those issues. And then it happened again, the application was slow
again. I think I pretty much tried it all, I'm out of answers so
anything will be appreciated.

Thanks,

Stephane

Since disabling SMB signing speeds up the db access, and then it reverts to
slow, presumably SMB signing is being re-enabled in spite of your GPO
changes. Maybe there's another GP object which is set to enable SMB signing?
I don't have the instructions at hand, but I seem to remember it had to be
disabled in at least 2 GPO's, one for the server and one for the clients.
You should be able to find instructions via Google.

Hi Paul, I'm pretty sure all my policies are good, but I have not
rechecked the policy on the workstations. I will check on that.
