Re: Login Redundancy

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Such redundancy is fairly well built in to the whole system, so long as your
forest is properly configured your clients should be able to find an
available DC in the event that one goes down.

So what do I mean by properly configured? Well you first of all have to have
your Sites & Subnets properly configured, a client tries by default to find
a DC to authenticate to that's in it's own site. If it cannot find one, it
will try to find any DC in the domain. The way it finds the DCs is by using
DNS, so clients must be configured with at least two DNS server addresses
for redundancy. Lastly, a Global Catalogue must be available at logon so the
GC role should be fairly widespread. If you have a single domain, make all
DCs a GC.

(This doesn't really relate to Group Policy by the way.)
