Create a DNS record
On the DNS server, create a hostname and corresponding “Host (A)” record for the virtual DCE that matches the Virtual IP (VIP) for the NLB. This is needed so that the virtual DCE name resolves to the VIP used on the NLB.
When installing DCE in HA mode, the installer prompts the user to supply a virtual server name. This virtual server name should match the DNS record previously created.
When configuring the MFP devices to connect back to the highly available DCE, the DCE hostname/IP Address should be the VIP for the NLB and not the individual DCE hostname or IP Address.
