Can DFS do this?

Hey guys, I have 2 servers that have users home folders,

file server 1 shared folder with users folders with last names A-L
file server 2 shared folder with users folders with last names M-Z

Can DFS provide a Domain-based DFS share that allows users to browse to one
share and see everyones home folders? I don't want to replicate the data
between the servers.

\\domain\home folders
user.a
user.b
user.m
user.z

Thanks!
MIke

Hello Mike,
Yes, you can use dfs to do that. You can have a root with name share,
homefolder etc, on both fileserver1 and 2
\\domain.com\share

Thanks Isaac, I seem to be having problems geting it to work.

When I browse to the dfs share, i can't seem to get the sub-folders from
both server's shares to show up under the dfs share, I can only get them to
show up seperate.

\\domain.com\share
server 1 home a-l share (folder)
server 2 home m-z share (folder)

What I would like to have happen is when someone opens the dfs share it
shows all of the user directories from both locations.
\\domain.com\share
user.a folder
user.b folder
user.x folder
user.y folder
user.z folder

Thanks,
Mike

Mike,
To do that, you will need to create dfs links on the root for each sub
folder.

Create a folder called "share" on both server1 and server 2 respectively,
make sure they both have similar permissions.
On server1, either manually create a root namespace, if you have not done so
already. \\domain.com\share
and then add dfs links for the respective folders to this namespace.
Example, first lnk would be user.a (Location will be \\server1\home a-l
share\user.a. Then, proceed to create the second link for user.b, etc

once you are done, go to server2 and create a fault tolerance which will
basically mirror server1. You can do this by using
dfsutil.exe \addftroot \server:nameof server2 \share:nameofshare.
Once complete, if you go to \\domain.com\share you should see all user.a -
user.z

Hi Mike, what you are seeing is expected behaviour. It is not possible to use
DFS to "join together" the home folders into a single list.

Think of this from the client perspective. It sees a UNC path
"\\Domain.com\DFSRoot\Homefolders". The client sees that Homefolders is a link
and retrieves the UNC path that the link points to (the target). Say it gets
\\server1\homeA-L, it then open \\server1\homeA-L and display the content. If
you also add a link on "Homefolders" to Server2\HomeM-Z then DFS treats this as
a redundant copy. It will resolve the name "\\Domain.com\DFSRoot\Homefolders" to
either \\server1\HomeA-L or to \\Server2\HomeM-Z. Once this name resolution is
done the client then redirects to the resolved UNC name and open it.

The client does not open both possible link destinations and merge the content.
Remember you can have up to 127 link destinations (replicas) spread through your
lan/wan infrastructure. These can be over slow links so imagine the time
required to resolve all 127 link targets, read their entire content and merge it
into a single list for the client. How many hours would this take.

The best you can do is create separate DFS folders with one for each target home
folder group. That is do not create links on "Homefolders!" but create
sub-folders HomeA-L and HomeM-L. Create links on these to the server home
shares. This will give you a name space like
\\domain.com\
homefolders\
HomeA-L
HomeM-Z

Of course you can then create fault tolerant replicas for either or move either
to a new server without the need to change the names the clients use.

Thanks Dave! Isaac's solution does work, but I can see what you are saying.
If the servers were spread out across multiple sites that could be an issue,
but all the servers sit in one location. And if you replace the homeA-L and
HomeM-Z with each individual users folder it does work, however one thing
that does raise red flags, is the limit you mention about of only having 127
possible links. That does raise concern because I have some 600 people at
this one location. I figured out how to script it to have it auto add every
users home folder, but thats going to hurt to find out that its gets through
127 and stops.

The 127 limit (looks like this may have increased to 256 now) is the number of
replicas you can have for each folder, i.e. Usaer1 can have multiple copies of
his home folder replicated to many (servers). You can have a lot more users
folders with individual FRS folders and targets. There are guidelines limits
though It is documented in
(http://technet.microsoft.com/en-us/l.../cc779936.aspx)

In the past there has been a lot of discussion about a 5000 folder limit but I
cannot find anything on this now.

Fat fingers :-) FRS should be DFS
