An error occurred while dispatching a duplicated socket: this handle is now leaked in the process

The error kept coming up in the System event logs on Microsoft Windows Small Business Server (SBS) 2011.

To fix this, change maxPendingAccepts from 2 to 10 in SMSvcHost.exe.config

<net.tcp maxPendingAccepts="10" ... >

New Brower Session on IE8/IE9 and Google Chrome

IE8 or IE9 (Microsoft Internet Explorer)
Use -nomerge switch when running IE.

Google Chrome (V12.0.742.124)

• Use Ctrl + Shift + N to bring up a new Chrome window in the Incognito mode (private browsing). However, any subsequent window opened up this way will share the same session.
• Use --user-data-dir switch with different profile locations when running Chrome. A bit awkward but can be mitigated by using shortcuts. However, each session will its own config and cache. For example,

google-chrome --user-data-dir=/home/tom/chrome-profiles/1
google-chrome --user-data-dir=/home/tom/chrome-profiles/2
google-chrome --user-data-dir=/home/tom/chrome-profiles/3
