I see this question fairly often in the DFS_FRS newsgroup. A customer will be setting up a new namespace and wonders whether he needs to move a bunch of shares under the root folder. The answer is simple: don’t use the root folder for storage. Keep your shares elsewhere and create folders in the namespace (aka links) that point to those shares. The Distributed File System service will create its own structures under the root, but there is no need for you to store files and folders there.
