Vista Runs Slowly on Windows Network

The Problem:

Many of you may have experienced this problem.  You try to connect your Vista machine to a Windows Network, but it hangs and is very sluggish.  You then try to copy files to or from a network drive and it seems to take hours.  A hundred MB should not take 9 hours to copy over 100 MB lines!

The Solution:

The solution is easy!  Just find the icon for your Command Prompt (All Programs -> Accessories -> Command Prompt).  Right Click on the icon and say "Run as administrator" and that will open a command prompt with Administrator Rights.  Then just type the following 3 lines into the command prompt, hitting Enter after each line to execute it.

  • netsh interface tcp set global rss=disabled [enter]

  • netsh interface tcp set global autotuning=disabled [enter]

  • netsh interface tcp set global autotuninglevel=disabled [enter]

How to fix Windows Vista speed issues when slow on network

  • Reboot your computer

This resolution will fix the tcp stack and once you reboot, things should run normally when access a domain or the network.

Good luck, and I hope that fixes your issues.
