If you’ve never used another Windows operating system in a networked environment, or you’ve always used Windows on stand-alone computers, the move to a networked computer environment may leave you thinking that Windows Vista offers slow performance on a network. Today, I’ll take a look at some potential explanations for Vista’s sluggishness on a network and what you can do to improve Vista’s performance.

Vista File Transfers Seem Slow

My first suggestion seems like a no-brainer, but many people neglect to take this step. Make sure your copy of Windows Vista is up-to-date. Install all security patches and updates that are available for Vista (or whatever Windows OS you’re using). You can set Windows Vista to automatically download and install critical updates. If you don’t have your OS configured to do this, you should consider taking this all-important step. If you can’t bear the thought of Windows Vista doing something without your express consent, you can have Windows Vista download the updates and ask if you want them installed.

If file transfers over your network seem slow, you may want to check the driver for your network adapter. Make sure you have the latest one and verify that the driver you’re using is meant for the adapter you have. Windows Vista doesn’t always choose the correct driver for your hardware and your slow performance could be related to an incorrect or outdated driver.

One of the biggest culprits in slow network performance is the firewall. If your firewall is not configured correctly, your network activity can grind to a halt in very short order. The firewall’s job is to reject packets that don’t belong, so it takes a look at whatever comes and goes across the network. While this type of inspection is generally good, you need to make sure that the services you use (like FTP, HTTP, etc.) can traverse the firewall without getting caught up in erroneously applied rules.

Firewalls are notorious for being either over-configured or under-configured out of the gate. Users may install a firewall and think they’re protected, when in reality, the default firewall configuration allows everything under the Sun to pass through. Oppositely, some firewalls are locked down completely and let nothing (or virtually nothing) through, making your network a very lonely place indeed. If you have a firewall installed, read the documentation carefully and understand which services must be allowed for your applications to function properly.

There are a few other causes of slow network performance worth taking a look at. I’ll discuss these in a future post.
