Are you using the Visual Studio 2008 Beta 2 VPC image? Be forewarned: The image expires on 1 November, 2007, not March 15th, 2008 as originally announced.
You’ve got only a couple days to work on getting your projects and TFS data off that box and on to another location. Microsoft’s put out some guidance on moving TFS data.
Microsoft put out word of this goof themselves and is asking the community to help spread the word. If you know anyone using this VPC then please pass word of this problem on to them.
One critical issue regarding this: Your data on that VPC will not be accessible after 1 Nov, 2007. Get cracking and move your data off to a safe location!
