We recently performed some planned weekend maintenance which required us to 
shut down our DFS file servers (among others) that we use to host users home 
folders (we have configured in AD). As we only started using the home folder 
feature this year we had yet to experience this but when the file servers 
were shutdown we noticed that domain logons would hang indefinitely.

It took a good 5 minutes for me to realize what was happening but when I 
disabled the home folder setting on my normal user account and was then able 
to log on that made it pretty clear.

What I'm trying to figure out now is if there is any group policy or 
registry setting that will allow the log on process to skip the home folder 
step (timeout) if the DFS share is not available for whatever reason. As it 
stands now, the DFS servers are a single point of failure for user logons 
which is not a good thing. Appreciate any feedback. Thanks.

I use DFS homed home folders and have never seen the logon hang indefinitely.
The mapped drive is simply not mapped. You may have some other issue at work
here.

I would suggest to use Folder Redirection and Offline Files. This way the 
data is always available locally cached until the DFS services or share is 
available.

I agree. If a mapped resource is not available, I've seen it 
significantly delay logons but never completely hang the system...
