This is because of some new network functions in Vista. Microsoft tried some different technology in vista network to make things easy, but finally it failed. It is not a common problem for all vista computers, if your computer has latest service packs, patches and hot fixes, you may not face these above problems.

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

Host entries in Host file

If you are using two separate network IP addresses in network servers or if you already know the IP address for particular server which you access by name frequently, the method will improve vista network very well.
Run command prompt as administrators (Right click on Command prompt and select ‘Run as administrator’.

Better to add the FQDN of a server if you are using domain ( eg – xzy.com)
You can add the internet servers’ addresses also; it will save some time in internet browsing.
You can add the NetBIOS name also, if any of your programs use NetBIOS names.

Remote Differential Compression (RDC) is made for transfer data over the network with compressed format to use minimal bandwidth. But unfortunately not all devices and operating systems (which came before Windows Vista) support this feature; there for this Remote Differential Compression (RDC) feature will slow down your network performance.
Remote Differential Compression (RDC) can be removed under ‘Control panel’ -> Programs and Features -> Turn Windows featured on or off.
Remove the tick and press OK.
The above Methods and Vista Network slow part 1 will solve the vista network slowness problem.
