DFS?s

[Hank B]

Help, We are trying to test DFS. I think it may be a
active directory issue OR just plain not made for this
purpose!
We want our clients to go to the "other" server if one
goes down. BUT on testing, the error is no DNS server
found, or no logon server available! Both servers are
domain controllers, The second got AD on set-up from the
first server. I have read and read, Is DFS not a good fail
over solution? THANKS in Advance! Hank B

DFS is a failover solution for providing multiple places to access shared
files and folders, it has nothing to do with providing logon authentication.
If your clients are unable to logon after a DC goes offline, then you have a
different issue. Most likely, the failed DC was housing the PDC FSMO role,
and you need to transfer or seize that role to another DC on your network.

Are the clients pointing to both DNS servers?

If they're only pointing to one DC for DNS then you've zero fault tolerance.
Have at least two DNS servers listed in DNS settings.

Also, ensure that both DCs **ARE** GCs.

GCs are required for logon.

DNS IS A MUST. Many people forget this when testing failover and DR. If
you're only pointing at the box that's down, how are you going to resolve
the DC and GC SRV records???
