Richard Berg from the Team Foundation Server team in NC has a couple of posts on his blog that will be of interest to you if you're a Visual SourceSafe user:
The Windows Vista version of Internet Information Services (IIS) does not support WebDAV, which blocks the use of the Internet Access feature of Visual SourceSafe for repositories hosted on Windows Vista. However, you can still access Visual SourceSafe over the Internet from Windows Vista. For more information, see Richard's blog.
