Sudhir Hasbe has been posting some really good information on his blog about configuring Team Foundation Server 2008. You may remember Sudhir from the Channel 9 interview I filmed with him a few months back. Sudhir and the feature team he works with are passionate about making Team Foundation Server easier to configure and administer, which is good news for the rest of us!
If you want to try out the betas of Team Foundation Server 2008 you have the option of downloading and installing the setup bits yourself, or just grabbing a pre-configuring VPC. Everything can be found here.
