From: OneginNH on 4 Feb 2010 08:16
Two months ago I completed an uneventful install of SBS 2008 for a company of
about 25 users on brand-new hardware. The only significance issues since the
install have been performance-related, specifically that browsing shared
folders on the server is very slow (displaying the contents of folders, for
example). Opening large documents and media files is also very slow, and at
least one server-based Visual Foxpro program which ran very fast under the
old Server 2003 server slows to a crawl with the new server. However, all
these woes disappear if the client is Windows 7 - the speed difference is
night and day! Is there something that can be done to tweak Windows XP to
perform better with SBS 2008? The client does not have the budget to
undertake a migration to Windows 7 at this time.

Should not be such (any) differences. Something else is going on. Is the
SBS the DHCP server for the LAN? Were all the computers joined to the domain
with the wizards.? Are all updates current? Do all devices use the same
switch?

Please post the results of the command:

ipconfig /all > c:\iptest.txt

from the server, and one each XP and 7 stations.

Please don't change anything, and please tell us which is which.

Hi Larry, thanks for your response. I apologize in advance for the length of
this reply.

To answer your questions:

Yes, the SBS server is the DHCP server for the LAN

Yes, all the computers were joined to the network with the SBS wizard (as a
side note, it came as a big surprise that I had to install .NET on all the XP
workstations in order to use the wizard. The .NET version install was
version 3, then it was patched to the latest 3.5 -- latest as of late
November 2009 anyway. The process was incredibly time-consuming but yes, it
was done for every XP machine and the wizard was used in all cases).

Yes, I am fanatical about Windows updates on all machines.

No, not all devices use the same switch. There are four switches and there
is no correlation between which switch the user is tied to.

Below are the ipconfig results for the server (first) and an XP workstation
(second). Unfortunately I do not have a Windows 7 machine on the network and
I am not able to give you the ipconfig for that box. I do, however, have
that box here in my office and although I would not be able to connect to the
network we are talking about, I could certainly post the ipconfig for however
it comes up when not attached to the network - if you think that would be
helpful).

BTW I realize that having the second ethernet connection on the server
(listed first in the ipconfig.txt) enabled is not recommended, and in fact I
will be disabling it in the near future. It was only enabled as an
experiment in light of this network slowness problem. I can assure you that
the speed issue existed before that NIC was enabled, whcih was only recently.

One other note, early on I contacted Intel about this becuase of a hotfix
that Microsoft has concerning a problem with the I/O Acceleration technology
in some of their network adapters. They seemed to know nothing about it (and
this was the file server group at Intel) and pointed me back to Microsoft. I
never installed the hotfix in question becuase it did not specifically match
the set up the customer has nor the exact circumstances, although it does
sound very close. The issue is discussed on kb 968991. But perhaps this is
the area I need to revisit. I just got cold feet when Intel didn't even know
about something that seemed to me like it would be such a big issue out there
in the world.

Thank you again for your help.

I'd verify that none of advanced networking stuff (TCP Chimney Offload,
etc.) is enabled on the server first, it tends to cause issues with older
PC's. Have you run the SBS BPA? Anything in the logs of the server or
clients?

Hi Al and thank you for your response. To answer your questions:

1) In regard to "advanced networking stuff" I'm not sure where/how to find
that kind of thing. I guess I can poke around. In calling Intel about this
I woudl have thought they could/woudl point me in this direction (if needed)
since both the server NIC and the workstation NICs are Intel (actually that's
not strictly true, one of the worst performers under Windows XP has a Realtek
NIC). But, yes, what you are suggesting has been on my mind ever since I ran
across that KB 968991 article that I mention elsewhere in this (rather long)
posting - problem with that 968991 article is that it doesn't strictly apply
to my circumstances. But it talks about Intel Advanced I/O stuff which is
what you are pointing me to. Why Intel wouldn't have known about such an
issue is a mystery to me and for these various reasons I have therefore held
off on applying the 968991 hotfix - do you think I shoudl do it?

2) In regard to the SBS BPA I'm a bit embarrassed to say that I had not run
it. Why? Because with the BPA for the Exchange piece built right in to the
O/S, I guess I assumed that the BPA tool for SBS would be built right into
the SBS console alongside all the other error checking that tool constantly
does. Anyway once I saw your note I immediately downloaded the SBS 2008 BPA.
Right off the bat I did show the only critical error (expected), which was
that the DNS A resource record was pointing to both NIC's on the server. As
mentioned elsehwere in this mammoth post, the second serve NIC got turned on
recently only as an experiemnt and it did not change things at all. Anyway
this mornign I shut off that second NIC again and ran BPA again and the
critical error is gone for DNS. There are no critical errors. The remaining
non-critical issues are, of course, of concern but I have no idea where to
focus/get started -- I need to solve the slow network problem before I do any
of the more refined fine-tuning stuff - as I'm sure you can appreciate. But
perhaps the key to my performance issus is in these issues, and I have posted
them below (below my next and last answer to your questions) -- if there is
any feedback you can provide I would most appreciate it.

3) You ask about logs on the server and the workstations. Yes I have
checked and not seen anything obvious but I agree, I need to do some careful
analysis there, which I will proceed to do. If you have any suggestions as
to what to focus on in the logs that would be appreciated.

Thank you and here are the issues shown by BPA at this time:
