Thanks for the help. I am now able to stay connected to the Internet on all four user accounts after I unchecked "use a proxy server" under the LAN settings. In testing the connection I opened Internet Explorer 8 and was successful under two user accounts but the other two user accounts indicated ad ons were not compatible and brought me to a program called "Windows Powershell". After running "Windows Powershell" I am still unable to open Internet Explorer under two of the user accounts but I am maintaining my Internet connection. Any idea what might be wrong?
