I use Parallels on my iMac with Lion OS X and Windows XP. Generaly speaking, my setup works very well. However, last week my computer was giving me headaches. I could start applications, do my work and send and receive email. However, I could not reliably access the internet.
Webpages would only load after being refreshed 3-5 times, or not at all. Streaming would stop playing right in the middle.
I tried wireless and Ethernet internet connections. I tried Safari and Chrome on the Mac side, Internet Explorer on the Windows side. Nothing seemed to resolve the issue.
Luckily, we have Apple Care so I was able to get some assistance direct from an Apple tech. Here is the simple solution I was given that I thought I would pass along.
- From the Apple menu, choose Go > Computer.
- Double-click Macintosh HD.
- Open the Library folder.
- Open the Preferences folder.
- Find the SystemConfiguration folder and drag it to the trash.
- Restart the computer.
Apparently it is not uncommon for network preferences to become corrupt. Throwing the SystemConfiguration folder away (it will automatically regenerate itself after you restart the computer) is a quick solution.

Sounds like a pretty simple solution, unless you run into the same problem on Windows PC. I just had the very same issue using Windows 7 and I finally tracked it down to a JAVA update. After I ran the java update it totally crashed the network preferences. It was a very frustrating issue and I finally had restore the OS from a previous system backup.
