Replicating User Profiles Between Sites (With or Without DFS) - Why it Should be Avoided

This article is part of Helge’s Profile Toolkit, a set of posts explaining the knowledge and tools required to tame Windows user profiles. Roaming user profiles seems like such a good idea at first, but it causes a myriad of problems in practice. One of these problems stems from the fact that the master copy of each profile is stored on a central file share. That file share needs to be accessible over a fast connection from all machines a user is logging on to, or logons tend to become very slow. This proximity requirement is easy to meet if only one site is involved, but what if users roam between different locations, or if terminal servers are distributed across several data centers? Unfortunately, there is no easy answer to this question.

User Profile and Home Directory Storage: Distributing the Load Across Multiple File Servers

This article is part of Helge’s Profile Toolkit, a set of posts explaining the knowledge and tools required to tame Windows user profiles. The easiest way to assign user profile and home directories is via group policy. But that can only be done per computer. There is no (simple) way to point different users’ directories to different file servers. So what? No problem at all, until the number of users is too large for a single file server to handle. This article discusses what can be done to spread the user load.
