Use the following procedures to configure the hardware and verify DNS settings. Repeat this procedure for every node in the cluster.
To configure the hardware
To prevent lost heartbeats on the private networks, and to prevent the Microsoft cluster from mistakenly declaring a system down, Veritas recommends disabling the Ethernet autonegotiation options on the private network adapters. Contact the NIC manufacturer for details on this process.
To verify the DNS settings and binding order
Ensure the public network adapter is the first bound adapter as follows:
From the Advanced menu, click Advanced Settings.
In the Adapters and Bindings tab, verify the public adapter is the first adapter in the Connections list. If necessary, use the arrow button to move the adapter to the top of the list.
Do the following:
In the Network Connections window, double-click the adapter for the public network to access its properties. In the Public Status dialog box, on the General tab, click Properties.
In the Public Properties dialog box, on the General tab, select the Internet Protocol (TCP/IP) check box and click Properties.
Select the Use the following DNS server addresses option and verify the correct value for the IP address of the DNS server.
In the DNS tab, make sure the Register this connection's address in DNS check box is selected. Make sure the correct domain suffix is entered in the DNS suffix for this connection field.
