Need Help Setting up a replicated DFS share

I have two servers in an AD domain connected via a VPN.  I want to set up the user profiles so that they are available on either AD domain controller so that the profiles do not have to travel over the VPN during login.  I've been told the best way to do this is via a replicated DFS sahre, but I've no idea how to go about setting this up.

Any help is greatly appreciated.

Hi,

This is a pretty good article for DFS config and replication - http://www.windowsnetworking.com/articles_tutorials/Configuring-Using-DFS-Replication.html

Do not do DFS over a WAN link unless you have Windows Server R2. Previous version of DFS uses your entire bandwidth till the replication is complete which will congest your network badly depending on the size of user profile. Windows server R2 has a setting where you can specify how much max bandwidth you can use for DFS replication.

Think over this...

DFS (Distributed File System) was first introduced in Windows 2000 as a way of managing shared disk resources across a network and making it easier for users to find and access these resources. Unfortunately DFS in Windows 2000 was somewhat limited in its capabilities, especially in regard to providing high availability in distributed multi-site environments but also in efficiently replicating shared resources over slow WAN links. These limitations made DFS in Windows 2000 something of a pain to work with, and Windows Server 2003 offered little in terms of improvements.

With the release of Windows Server 2003 R2 however, a fresh release based on Windows Server 2003 Service Pack 1, DFS has been significantly enhanced in several ways. In this article and several following on WindowsNetworking.com, I’ll describe these enhancements and show how to implement them in various enterprise scenarios.

This from one of his articles.  I do not have R2, I have SP1.

Thank you for your thoughtful approach!

Given that I do not have R2, what would the options be considering my situation?  (Or is R2 a free aand relatively pain-free upgrade?)

Great Question......

First of all, R2 is NOT FREE. You have to pay upgrade price...

But the good news is upgrade is a Breeze. you have to do a forest prep and domain prep to prepare the forest for new AD. And only install 2nd cd which will install only R2 components. So its not like a OS upgrade...

Other than that your option is to use third party products that optimize replication data over the wan but again without DFS roots, you cannot use that for your romaing profile since your profile will be pointing to the original location..

So i should say weigh your options. See how badly you need this and how much good would it do . Consider the upgrade price for 2 servers since you need to have R2 in each root. See if the money is worth....

Well, I know that downloading a 500 MB profile over the wan every time I log in is not an acceptable solution.  Third part options are not what I want to be messing with.

I can't be the first guy who wants up to date profile date at both locations am I?

I definitely dont think you are the only person researching having updated profiles on geographic locations...

But the solutions are pretty limited over wan bandwidth...

If you absolutely need it, just upgrade to R2. Otherwise its going to be hard if not impossible....

I think admins have always had problem maintaining data current over wan links no matter whether it is a profile or file share...

Or just wait to see if anyone else suggests any solutions...I  dont have any for you..sorry..

Lets suppose for a minute that I want to do this anyway and see how bad it is on SP1.  Can anyone guide me through the steps or send me a link to a document that covers it succintly?
