Re: DC Temporarily Off-line, Remaining DC Struggling

Tech-Archive recommends: Fix windows errors by optimizing your registry



This is probably because the DC that is temporarily down is also the DNS
server. Make sure that ALL TCP/IP clients use both DCs as DNS servers.

Don't worry about that error:

You transfer the DM via AD Trusts:

If you also use DHCP you might want to consider making both DCs DHCP servers
and using the 80/20 rule. Or, as I prefer, the 50/50 rule. This is where
you create the same scope on both and exclude half the addresses on one
server and the opposite half on the other.
