I needed to restrict a computer in a public area to specific URL related to HR sites. I found this article on taking care of this in Internet Explorer.
Boutell.com

To summarize: create a IE ratings file with the following content to restrict everything.

(
(PICS-version 1.0)
(name "Thumbs Down")
(description "A fake rating service that doesn't rate anything.")
(rating-system "http://notreally.madeup")
(rating-service "http://notreally.madeup")
(category
(transmit-as "Please Use The Approved Sites Tab Instead!")
)
)


Save as c:\windows\system32\thumbsdown.rat
Open up IE > Tools > Internet Options > Content > Content Advisor
Turn it on and click ok
Goto General tab
Make sure Users can see sites that have no rating is not checked. Leave supervisor can type a password to allow users to to view restricted content checked.
click on Ratings system and remove any previous installed ones.
Click and add the one that was just created and saved.
Click on Approved sites tab and type sites that you want to allow access to.
Then click always.

I was attempting to upload a theme for a new WordPress install and I kept getting an error that read.
The uploaded file could not be moved to /var/www/vhosts/domain.com/httpdocs/wp-content/uploads

What had happened was when I created this site I did not uncheck the default setting of Plesk 9 for PHP safe_mode

I have had a network client who for sometime has reported losing his connection to the network and being forced to reboot to reestablish the connection. Because of the intermittent nature of this problem I have as yet to solve it. This will be a record of future steps taken to fix this problem. I opened our network monitoring device 3COM Network Supervisor. I noticed that the machine in question was being monitored. I turned it off and will wait to hear from the client if this still occurs. If so I will investigate the Auto detection of his network adapter.  I will use the following article in working with this.

They lost connection again and so I have opened up a specific app for this on the clients machine called Broadcomm Advanced Control Suite.
I did not have an option to go to 1000 mbps. I did set it at 100 Mbps at full duplex. I will wait and see if this takes care of the problem. All the diagnostic test run via the Contol Suite passed.
