We have about 5 DC's in our main site. There are a plethora of applications that need a DC hardcoded into their code to for either LDAP queries, or authentication.
At the moment, they are all pointing to DC1.
Obviously, if DC1 goes down, then we are in trouble.
I woud like to look into load balancing across all 5 DC's. I guess I could create a DNS CNAME (ldap.kam.uk) that points to all the DC's, but if one of the DC's is down, this won't help much. Does anyone have any ideas how I can implement some redundancy?
