All About Microsoft posted a news story that the Windows Home Server 'Vail' Release Candidate has been released

For those Windows Home Server (WHS) loyalists hoping against hope that Microsoft might reconsider its decision to cut Drive Extender from the coming ‘Vail’ release, your prayers have NOT been answered.

Microsoft is delivering the Release Candidate (RC) test build of Vail — Windows Home Server 2011 – on February 3, and there is no Drive Extender included. There’s also no Drive Extender in “Aurora” — Small Business Server 2011 Essentials – a Vail sibling for which Microsoft also is delivering an RC build today.
