I have a networked Windows 7 64 desktop workstation on a Gigabyte network connection with a Dell SC 1430 Server 2003 which is the Domain Controller. The server simply provides file & print services as well as a SQL Server 2008 R2 instance. Starting about two months ago, performance thru my SQL Client app and File Explorer has been terrible. I have search the internet until blue and the few things I have found, have not affected the performance either way. I have a Windows 7 x86 Laptop that connects to the same network on a 10/100 nic and there is not a performance problem.
I have tried:
- Disabling the Background intelligent transfer service
- netsh interface tcp set global autotuninglevel=disabled
- Disabling the IPV6 interface
- Turning off the LLMNR protocol via the GPEdit.msc
I did see a couple of notes out there of some people just reinstalling Windows 7 and the problem went away until the Windows Update brought the install up to date.
Anyone have any ideas on how to fix this?
