Can I still use Microsoft Virtual Server or Microsoft Virtual PC to test Windows Server 2008 clustering?

Virtual Server has commonly created a shared disk over the emulated SCSI controller to use for clustered storage. However, Server 2008 clustering doesn’t support parallel SCSI.

But there is light at the end of the tunnel. Server 2008 clustering supports the majority node set model, which means a cluster doesn’t need shared storage. Server 2008 can use node-voting with three nodes or more, or a file-share witness instead of the quorum disk for two-node clusters.

If you want shared storage, the easiest option is probably iSCSI because the iSCSI initiator is built into both Server 2008 and Windows Vista. For the iSCSI target, you may have access to an iSCSI SAN/device, a software solution such as Windows Storage Server, or an add-on iSCSI

What is the /admin switch in Microsoft Terminal Services Client (MSTSC) for Windows 2008 and Vista?

Although the /console switch no longer has any effect on Server 2008 and Vista Terminal Server connections, a new switch called the /admin switch has a similar effect when you use it to connect to a Server 2008 server with the  Terminal Services role. When you use this switch with MSTSC, connections don’t consume Terminal Services CALs.

The /admin switch involves elevated rights. If a user has the authority to use the /admin switch but has been marked with Deny Users Permissions To Log On To Terminal Server, he or she will be able to connect using mstsc /admin. Also, if a terminal server is in drain mode (no new sessions are accepted), an /admin session can still be created. The /admin sessions don’t count toward the session limit that may be configured on a terminal server to limit the number of sessions.
