Yesterday I received information that there was a timing issue in the VS2008 Beta 2 VPCs. The effect of this timing issue is that the VPC will expire early and that is only in a couple of days from now on Thursday, November 1.

The VPC expires at the operating system level and that makes it impossible to extend the timeout period for the VPC. This is important because if you have information stored in the Team Foundation Server you need to move forward it is recommended that you backup the TFS databases as soon as possible to be prepared for the new VPCs.
