Sounds like SMB2 spirit.

From: Dustin on 1 Jul 2010 11:07 Generally, problems encountered with XP clients versus 2008 servers are caused by SMB2. A workaround for this problem is to turn SMB2 off on the server. 1.Run "regedit" on Windows Server 2008 based computer. 2.Expand and locate the sub tree as follows. HKLM\System\CurrentControlSet\Services\LanmanServer\Parameters 3.Add a new REG_DWORD key with the name of "Smb2" (without quotation mark) Value name: Smb2 Value type: REG_DWORD 0 = disabled 1 = enabled 4.Set the value to 0 to disable SMB 2.0, or set it to 1 to re-enable SMB 2.0. 5.Reboot the server.

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 did not 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.

Hi Al and thank you for your response. To answer your questions: 1) In regard to "advanced networking stuff" I am 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 is 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 does not strictly apply to my circumstances. But it talks about Intel Advanced I/O stuff which is what you are pointing me to. Why Intel would not 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 am 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 am 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.

Russ Full Details here! *This is a edited repost of an earlier Microsoft message. (No this is not a joke) - Russ Grover MVP What is Happening? This message is to inform you that Microsoft will soon begin discontinuing newsgroups and transitioning users to Microsoft forums. Why? As you may know, newsgroups have existed for many years now; however, the traffic in the Microsoft newsgroups has been steadily decreasing for the past several years while customers and participants are increasingly finding solutions in the forums on Microsoft properties and third party sites. This move will unify the customer experience, centralize content, make it easier for active contributors to retain their influence, mitigate redundancies and make the content easier to find by customers and search engines through improved indexing. Additionally, forums offer a better user and spam management platform that will improve customer satisfaction by encouraging a healthy discussion in a clean community space. To this end, Microsoft will begin to progressively shift available resources to the forums technology and discontinue support for newsgroups. In addition to offering a compelling online browser experience, for those users who prefer to use an NNTP (newsgroup) reader to participate in the newsgroups community, we have developed a solution called the NNTP Bridge which allows a user to connect a variety of supported NNTP readers to the forums they would like to participate in and continue having the NTTP reader functionality. You can find instructions on how to download and set up the Microsoft NNTP Bridge http://connect.microsoft.com/MicrosoftForums/ Which Newsgroups Are Affected by this Shutdown? All public newsgroups will eventually be closed between June 1, 2010 and October 1, 2010. Microsoft will be closing newsgroups in a phased approach, starting with the least active newsgroups and moving eventually to more active ones throughout the course of the next six months. Where Should I go with the Closure of this Newsgroup? Microsoft has a large selection of forums, many of which cover either the same or closely related technologies to the ones found in the newsgroups. The forums have seen amazing growth and are an excellent place to continue the discussion.
