Vista client extremely slow when browsing SBS 2003 R2 SP2, whether on the domain or not, browsing a folder after username authentication takes about 30 seconds every time you click a folder. Any ideas please

Hi, Thank you for your post. I would like to confirm if it takes around 30 seconds each time you open a share folder on Windows SBS 2003 server from the Windows Vista machine. Please perform the following steps to troubleshoot the issue: 1. Turn off Auto Tuning on the Windows Vista machine:--------------------a. Click Start, and type cmd in the Start Search box. b. Right-click the cmd icon, and select Run as Administrator.c. In the Command Prompt, type the following command:netsh interface tcp set global autotuninglevel=disabledd. After that, please check the result.Note: Please re-enable Auto Tuning by typing the following command if the above steps cannot fix the issue:netsh interface tcp set global autotuninglevel=normalIf the issue persists, please install the update KB938194 and KB938979, and refer to the solution in the KB article 936594 (http://support.microsoft.com/kb/936594). Hope it helps. Sincerely, Joson Zhou Microsoft Online Community Support
