If Windows Vista Network is Slow, Try These Steps – Part 2

This is the second part of our earlier guide how to make Windows Vista network faster. Here you will find additional steps which can be tried if you still face network slowness on you Windows Vista laptop or desktop.

As we said earlier, the latest network technology introduced in Vista OS creates trouble in network communication with older Operating Systems or legacy devices. To overcome this issue, we can disable some of the latest networking features. Disabling ‘autotuning’ function will surely improve the network speed in Vista. But if it doesn’t help in improving the network speed, try below extra steps.


Additional Steps to Make Vista Computer Network Faster

1) Make sure that you have already followed the steps in our earlier guide Vista Network slow – part1

2) Disable IPv6 if you don’t use

Right click on your Local Area Network connection and open properties.

Vista Network Slow

Remove the tick from IPv6, press OK.


3) Clear DNS Cache

Run command prompt as administrator (Right click on Command prompt and select ‘Run as administrator’.

ipconfig /flushdns

This will clear the DNS cache (entries) on your pc, so any previous wrong DNS entries will be cleared and new requests will go to DNS server.

4) Host entries in Host file

This method helped me lot to solve vista network slowness issue and improved the speed very well. If you are using two separate network IP addresses on network servers or if you already know the IP address for particular server which you access by name frequently, this method will improve vista network very well.

Run command prompt as administrators (Right click on Command prompt and select ‘Run as administrator’.

Go to: System folder\system32\drivers\etc

Edit the host file with appropriate server names and addresses,


Better to add the FQDN of a server if you are using domain ( eg – xzy.com)

You can add the internet servers’ (URLs) addresses too; it will save some time in internet browsing.

You can add NetBIOS names too if any of your programs use NetBIOS names.


5) Remove Remote Differential Compression

Remote Differential Compression (RDC) is to transfer data over the network in compressed format to use minimal bandwidth. Unfortunately not all devices and operating systems (which came before Windows Vista) support this feature; therefor Remote Differential Compression (RDC) feature may slow down your network performance.

Remote Differential Compression (RDC) can be removed under ‘Control panel’ -> Programs and Features -> Turn Windows featured on or off.

 remote-differential-compression vista

Remove the tick and press OK.

We hope these additional steps would be helpful in fixing Windows Vista network slow issue.
