One problem though is that if the profiles are huge, or scattered across a
WAN or busy LAN, isn't there a potential problem with timeouts leading the
client to get halfway through the profile download or upload and then having
to re-poll the DFS tree? If it has to start the process over, or continue it
this could glitch the profile process, or, what if the client is then
re-directed to a different version of the profile on a different store?
the other thing you mentioned is that you use a NetApp, which I also put in
my frist reply. I am not sure that DFS is as elegant or reliable when using
NT file servers.....

If you're talking about Microsoft's Distributed File system, I've heard that
comment before about DFS & user profiles... it's a bunch of baloney. DFS is
a file system redirector... you connect to the tree, the tree tells you
which server to connect to & its out of the story. The only communications
back to the DFS tree are when your SMB session state times out or the file
share becomes unavailable. I don't remember how long the session time out
it is, but its a pretty good amount of time. If your SMB session state
times out, the client goes back to the DFS tree, asks again which server do
I connect to & starts over. If a server connection dies, it goes back to
the tree after it's complete with it's retry routine, and asks the tree for
the next server sharing that DFS leaf (incase you're using a DFS leaf
against multiple servers).
I've been using DFS against a Netapp 860 cluster with 8000+ shares (& a 760
before that)... close to 2000 of them are WTS profiles... never, ever heard
a peap. In fact because of DFS, I've moved data from one volume on the pair
to another volume on the partner & with ZERO downtime... thank you
SnapMirror & DFS.
My humble opinion is to fire away... DFS is just a redirector...

Subject: [THIN] DFS and Profiles
I've been doing some research on using a DFS Share to store user profiles.
From what I understand, it is generally not recommended to store profiles
on a DFS as DFS was not designed to handle it. Also, there are examples of
systems that are currently using DFS to store profiles. However, I cannot
find any concrete information that supports one theory over another.
Does anyone know of any white papers, faq, anything that might be of help?
