I may be on the wrong track However we had issues with 64bit windows 7 clients we run an ip4 network internally and found this solved our problem
1) Run the following commands through a CMD prompt with Admin rights. netsh interface tcp set global autotuninglevel=disabled netsh interface tcp set global rss=disabled 2) Turn off Remote Differential Compression - RDC Go to Control Panel => Programs => Turn Windows features on or off => Deselect "Remote Differential Compression" 3) Set "Link Speed and Duplex" in network card properties from "Auto Negotiate" to match your line speed of your switch. In my case this was "100 MB Full Duplex" 4) Deselect "IPv6" and "QoS" in network card protocols Reboot your PC Nigel Parker Systems Engineer Ultraframe (UK) Ltd Tel: 01200 452329 Fax: 01200 452201 Web: www.ultraframe.com <http://www.ultraframe.com> Email: mailto:nigel.par...@ultraframe.co.uk <mailto:nigel.par...@ultraframe.co.uk> From: listsad...@lists.myitforum.com [mailto:listsad...@lists.myitforum.com] On Behalf Of Jimmy Tran Sent: 03 January 2014 15:42 To: ntsysadm@lists.myitforum.com Subject: [NTSysADM] Windows 7 and Windows Server 2008 R2 file transfer latency Hi All, I previously posted a message about slow file opening and saving in office 2010 between W7 and Server 2k8r2 but had no replies. I did further testing and it seems to occur more than just office files. It occurs with any "opening" or "closing/saving" of files on the server. Once it is opened, it works fine. There was a hotfix that was supposed to resolve this issue, http://support.microsoft.com/kb/981711, but I couldn't even get that installed. I follow some other posts and disabled SMB 2.0 of my W7 client. The latency went away. Ideally, I'd like to have SMB 2.0 enabled. I'm sure someone here on this board has had this issue? Can anyone shed some light on what they did to resolve this? I'm about ready to open a support case with MS but I thought I'd try this team one more time.
