Let us say you have CSS on Isaserver1.contoso.com which also has firewall service on it i.e. its acting both as CSS server and firewall node and you have another node isaserver2.contoso.com which is acting as firewall node only. This ISA server array is part of a domain called contoso.com. We plan to configure CSS replica on Isaserver2.contoso.com, but when we do that and start the installation on the Isaserver2.contoso.com for css replica we get error "setup failed to install ADAM in replica mode (0x80074e46)"
We will get this error if we have not added new css replica i.e. Isaserver2.contoso.com in the replicate CSS server group in the system policy at the enterprise level So we need to edit the system policy at the enterprise level , add the FQDN and the IP of the new CSS replica in replicate CSS server group save and apply the settings Then install the css replica and it shall install it successfully as shown below.
