Microsoft offers a number of VHD downloads at Microsoft Download Center. You can find ready to go/test virtual hard disk images of:
- Windows Server 2003 R2
- Exchange 2007 and Microsoft Live Communications Server 2007
- ISA Server 2006
- SQL Server 2005
- Microsoft Dynamics CRM 3.0 Virtual PC demonstration
The Dynamics CRM demo VHD contains a complete server with Windows Server 2003, Active Directory, SQL Server 2005, Exchange Server 2003, Microsoft CRM and Visual Studio 2005.
This is a great step forward and will make testing of beta server products more efficient. I guess there will be a MOSS 2007 VHD available soon…
