A remote office with 1 DC/GC and 1 file server. Clients get DHCP from the
DC. If the DC is turned off, will the clients still be able to access the
local file server, as long as their DHCP lease hasn't expired? I realize,
that in theory, that's what a lease does. But I've never tried it. And
this is a live environment, not a test lab.

I realize if the GC is unavailable, and they logout, they won't be able to
log back in to the network.

My main concern is access to the file server.

As long as they have a valid IP address in the same network then they will
have access to any resources in the network. Although the user will not be
able to login to the DC because it is not available they should be able to
login to the network, of course anything that you authenticate to through
the DC you will not have access to.

Be careful, I've had more than one client try to renew its DHCP lease
half way through the lease life and give up the lease, before it
expired, because it could not reach the DHCP server to renew its lease.

If you have the file server there, why not make it the the DHCP server
or a secondary DHCP server? (Or is the file server some sort of NAS
appliance?)

Would not recommend. I'm doing a similar thing, but seems clients sometimes
lose the lease even if it should still be valid.
